Try closing and reopening the Tesla app.
If that does not correct the issue, try rebooting the Tesla screen computer (Press and hold the left and right steering wheel scroll wheels for longer than ~6 seconds.) Do this while your Tesla Model Y is parked. The screen will go dark and the Infotainment computer that controls the screen interface will reboot after several minutes.
Lastly, you could log out of your Tesla account on the Tesla app and log back in. You will need the password for your Tesla account.
Other considerations:
Did you add a new second user profile to your Tesla Model Y? Multiple user profiles reportedly can cause issues with Cabin Overheat Protection.
Have you given the access credentials to your Tesla account to any third party applications for energy monitoring, charging, Apple watch automation etc. ? Third party apps can cause issues with the Tesla charging settings and climate control settings.
