If you're having trouble downloading the app, make sure your device has enough free space. If your memory is full, you can free up space by deleting old apps you no longer use.
If there's sufficient space, try these steps to fix issues with Google Play:
Open your device’s Settings app.
Tap Apps & Notifications > See all apps.
Scroll down and tap Google Play Store.
Tap Storage > Clear Cache.
Then, tap Clear Data.
Reopen the Play Store and try downloading the app again.
If the issue persists after clearing the cache and data, restart your device:
Press and hold the Power button until the menu appears.
Tap Power off or Restart (if available).
If needed, press and hold the Power button until the device turns on again.
