mac m1 downgrading from big sur 11.3 to 11.2.3

Have not tried as have zero issues moving from 11.2.3 to 11.3.

If you want to downgrade back to 11.2.3 there might be two methods, both required due diligence on the part of the User ( you )

1 - A Time Machine Backup rare-dating the application of 11.3

2 - a Bootable Clone of 11.2.3

Otherwise - do not see a way back to 11.2.3. Not even Nuking the drive and reinstalling Exception - have a Bootable Installer of 11.2.3 in hand.

you mentioned you had no issues upgrading to 11.3, so all of you ios apps that were sideloaded still works?

FWIW, Apple started blocking side loading apps as of 11.2 and 11.3 beta. 11.3 also introduced an important security patch. Personally I wouldn't want to be stuck on 11.2.3.

Do not use this feature. macOS on computer and iOS on iPhone. the two only communicate via iCloud and Sync back and forth. All personal preferences to keep then separate.
