I think it has something to do with some setting in the Google Photos app.
Turn back up & sync on or off
- Open the Google Photos app.
- Sign in to your Google Account.
- At the top right, tap your account profile photo or initial.
- Select Photos settings and then Back up & sync.
- Turn back up & sync on or off.
If you see a message asking to allow the app to access your photos:
- Open the iOS settings app and tap Privacy and then Photos.
- Turn on Google Photos.
Change your backup settings
- Choose the Google Account to back up photos and videos: Under 'Backup account', tap the account name.
- Change your upload size: Tap Upload size.
- Back up on mobile data: if you don’t want to wait for Wi-Fi to back up your photos, under 'When to back up', tap Use mobile data to back up photos or Use mobile data to back up videos. Service provider charges may apply if you upload using your mobile network.
Check if your photos have been backed up
- On your iPhone or iPad, open the Google Photos app.
- Sign in to your Google Account.
- At the top right, tap your Google Account profile picture.
- You can view if the backup is complete or if you have items waiting to be backed up.
Costs to back up
As of 1 June 2021, any new photos or videos that you back up in Storage saver quality (previously named high quality) or express quality will count towards your Google Account storage. Photos and videos backed up in original quality will continue to count towards your Google Account storage.
Each Google Account comes with 15 GB of storage.
Important: Any photos or videos that you’ve backed up in high quality or express quality before 1 June 2021 won't count towards your Google Account storage.
