Hi there! Thanks for reaching out about the "cannot connect too many devices" error on the STARZ app. It sounds like the system is detecting multiple devices already signed in with your account, which can happen if you've used the app on several devices before.

To help you better, can I ask:
- How many devices have you recently used STARZ on?
- Have you shared your account with family or friends?
- Did you try logging out from other devices or the STARZ web portal?

Meanwhile, here’s what you can do step-by-step:

1. Sign Out of Other Devices
STARZ limits the number of concurrent streams or signed-in devices. To fix this, log out from STARZ on other devices you no longer use or haven't logged out of.

2. Use STARZ Website to Manage Devices
Sometimes, you can manage your connected devices by logging into your account on the STARZ website:
- Open a browser on your Mac and visit starz.com
- Log into your account
- Look for a section like "Account Settings" or "Manage Devices"
- Remove any devices you no longer use or recognize

3. Restart Your Mac & App
Simply restarting your Mac and reopening the app can refresh the connection.

4. Update the STARZ App
Ensure the app is updated to the latest version. Although on a Mac, if you’re using the browser, make sure your browser is up-to-date.

5. Clear App Cache (If Applicable)
If you're using a STARZ app on your Mac and it allows, try clearing the app cache via system preferences or app settings.

If after these steps you still see the error, it might require contacting STARZ customer support to reset your device connections from their end.

Let me know if you want, I can help you navigate the website to remove devices or provide detailed app instructions on your Mac. Are you trying to use the STARZ app, or are you accessing STARZ via a web browser?
