Hi! I understand you're having trouble with the Denon AVR app not showing the link to the HEOS app, and also the AVR source options aren't appearing in your sources list. Let's try to get this sorted out together.

First, to clarify:
- Are you trying to see the AVR source inputs (like CD, AUX, or HDMI inputs) within the HEOS app on your iPhone running iOS 18.7?
- And when you say the Denon AVR app doesn’t display a link to the HEOS app, do you mean the apps don't seem integrated or connected to each other?

If that's right, here are some step-by-step troubleshooting tips you can try:

1. Restart both the Denon AVR and your iPhone.
Power off your Denon AVR completely, unplug it from power for about 30 seconds, then plug it back in and power it on. Also, restart your iPhone. This refresh helps both devices reconnect properly.

2. Check HEOS App Settings to Reset Controller:
In the HEOS app on your iPhone, go to Home > Settings > Help > Reset Controller. This can restore missing source tiles on the Home page under "Sources." Sometimes these tiles don't show until reset.

3. Ensure your Denon AVR firmware and HEOS app are fully updated:
Sometimes, older firmware can cause the app not to display source inputs. Check for the latest firmware for your AVR on Denon's official support site and confirm your HEOS app is updated from the App Store.

4. Verify Network Connection:
Both your Denon AVR and your iPhone need to be on the same Wi-Fi network. If there are multiple networks or guest networks involved, the apps may not communicate properly.

5. In HEOS App, Check Device and Source Grouping:
Navigate to Settings > My Devices in the HEOS app, select your AVR device, and check for any grouping or audio settings like TV Sound Grouping that might affect source visibility.

6. Reinstall the HEOS App:
If the above steps don't restore the inputs, try deleting the HEOS app and reinstalling it from the App Store. Sometimes app cache corruption can cause display issues.

If after trying all these the AVR source options still don't show in HEOS, it could be a more specific issue with your particular AVR model or app version. In that case, please let me know the exact AVR model number, and we can look deeper.

Are you comfortable trying these steps now? Let me know if you run into anything or if I can clarify further!

Denon AVR app does not display link to HEOS app. AVR source options do not appear in sources option.

Thanks for sharing your concern again. It looks like the Denon AVR app is not showing the link to the HEOS app, and the AVR source options are missing in your sources list. Let's go through some targeted steps to address this based on what’s common with this issue and the latest guidance I found for iOS 18.7 on iPhone:

1. Reset Controller in HEOS App:
Open the HEOS app, then go to Home > Settings > Help > Reset Controller. This often restores missing source tiles (inputs) on the Home screen under the “Sources” section. It basically refreshes the app’s connection to your AVR’s input options1.

2. Power Cycle Your Denon AVR:
Unplug the AVR from power for about 30 seconds, then plug it back in and turn it on. This AC power cycle can fix communication glitches between the AVR and apps5.

3. Check Network Connection:
Double-check that your iPhone and Denon AVR are connected to the same Wi-Fi network and not connected via different frequency bands or guest networks, which can block app-device communication2.

4. Firmware and App Update:
Ensure your Denon AVR firmware is fully updated via the Denon support site or its own menu, and confirm your HEOS app is updated in the App Store.

5. Reinstall HEOS App:
If nothing works so far, delete the HEOS app from your iPhone and reinstall it fresh from the App Store. This clears app cache or corrupted data that can prevent the app from showing AVR sources3.

6. Check AVR Input Assign Settings:
On your AVR, go to Setup Menu > Inputs > Input Assign and verify that the inputs (sources) you want to see in the HEOS app are enabled. Some models let you hide inputs from the app via this menu6.

If you can share your exact AVR model, I can help look up model-specific tips. Meanwhile, try these steps in order and let me know how it goes. I’m here to help you get your HEOS experience smooth!
