Hi there! I understand your Revolut app on your Mac isn't starting, and I'd like to help get that sorted for you.

First, just to clarify, are you using the Revolut app via a dedicated Mac application or through a web browser on your macOS 10.15.7 system? Also, do you see any error messages when you try to open the app?

Meanwhile, here are some basic steps we can try together:

1. Restart Your Mac: Sometimes a simple restart can clear temporary glitches that prevent apps from starting.

2. Ensure Your App Is Up to Date: If you are using a Mac app, check for updates via the App Store or wherever you downloaded it, and install the latest version.

3. Check Internet Connection: Make sure your Mac is connected to the internet since the app needs online access. You might try switching between Wi-Fi and wired connections or resetting your router.

4. Close Background Apps: Quit any unnecessary apps running in the background that might be conflicting with Revolut.

5. Clear App Cache (if applicable): On Mac, apps sometimes store cache files. Locate Revolut’s cache (usually in ~/Library/Caches/) and delete its folder to reset temporary data.

6. Reinstall the App: If the app still won't start, uninstall it completely, restart your Mac, and then download and install the latest version again.

If you’ve already tried any of these, please let me know which ones, and we can go deeper with troubleshooting. Also, if you can share any app logs or screenshots of what happens when you try to launch the app, that would help a lot.

Not starting on android

Thanks for letting me know it’s the Revolut app on Android that won’t open. To better assist you, could you share a bit more? For example, are you seeing any error messages when you try to open the app? Also, what Android version and device model are you using?

In the meantime, here’s a step-by-step guide for troubleshooting this issue on Android:

1. Stable Internet Connection
The app requires a reliable network to open and sync correctly. Ensure you have a stable Wi-Fi or mobile data connection.

2. Update the App
Go to the Google Play Store, find the Revolut app, and check if an update is available. Installing the latest version solves many startup issues.

3. Clear Cache and Data
Sometimes cached data gets corrupted. To clear it:
- Press and hold the Revolut app icon, tap App Info.
- Go to Storage & Cache.
- Tap Clear Cache first, then try reopening the app.
- If it still doesn’t open, repeat and tap Clear Storage/Data (note: this logs you out, so have your login details handy).

4. Restart Your Device
A restart can refresh system resources that might be blocking the app launch.

5. Check for OS Updates
Make sure your Android system is updated to the latest version available for your device, as outdated OS can cause compatibility issues.

6. Check for Root or Custom ROM
Revolut does not run on rooted devices or devices with unlocked bootloaders. If your device is rooted or running a custom ROM, this might cause the app not to open.

7. Reinstall the App
Uninstall Revolut completely, restart your phone, then reinstall from the official Google Play Store.

8. Device Compatibility
Some older devices or very new Android 15 versions have reported compatibility issues. Checking Revolut support or system status pages for any ongoing issues might help.

If you’ve tried some of these steps already, please let me know which ones so I can focus on what’s next.
