Go to phone settings, then apps, find the Google Play Store app, and clear its app data. It might have mistakenly flagged your phone as incompatible with the app.
Also, if the ChatGPT app displays the message:
“Something went wrong. Please ensure your device’s date and time are set correctly. Check your internet connection, then restart the app and try again.”
Clear the Google Play Store’s app data; it might have misled the ChatGPT app into thinking your phone is incompatible.
I did that, and it fixed the issue for me, try.
Note: Clearing Google Play Store’s app data won’t delete any of your files or data. All your Google Play Store data is synced with your Google account, so the app will quickly reload the data once cleared.
