Have same situation on Switch v1.14.30 (current). Auto-doors remain closed, even with redstone torch. However, iron door in my basement works fine. Has opened after the incident started, but is closed, not working, now. Saving/Start doesn't fix it. Doors have been working fine for weeks before, and same system is still working on another world.
I found the problem with my iron doors locking on Switch. With the setting 'All Day' to ON, doors are locked. Probably do to the redstone light sensor. I reset the setting and doors work fine now.
