See the release note that this HN thread links to ;-)

>>> Background backup improvements Background backup on Android is now significantly more reliable. Previously, the background backup on Android was limited to newly taken photos. Now, the app uses a new periodic task scheduler, which allows you to upload your entire library in the background, and it plays nicer with Android's background execution limits, properly cleans up tasks, and warns you when battery optimization and notification settings might interfere with backups.

On iOS, the background refresh task now runs its sync and upload work in parallel, so uploads actually start within the short time window iOS allows.
