Autofocus stops at 3 clicks in batch mode

[stackedbeer]

Device: OnePlus 6

OS: Android 9 (Oxygen 9.0.9)

Issue: After 3 clicks in batch mode, the autofocus locks on and doesn't take pictures further.

Will have to enter Edit section, tap on Add page > Take another photo for every 3 pictures captured.

Issue persists even after a phone reset.

This is annoying and I'm having to currently take pictures on the Camera app and then batch edit/add rest of the pages.

Note: This does not occur on my Honor 8 running android 8.

Any help would be appreciated!
