I've been using the SchedulerCard plugin for months with no problem. Suddenly the card's layout is corrupted and what changes I can make on the card are not saved. In particular, I cannot change the schedule.
I've got v4.0.16 of SchedulerCard which is not the latest, but I can't update without updating Home Assistant itself (I have 20205.4.2), and I can't upgrade that without new hardware (I have a RPi3 with ARMv7). But it was working, and now it's not, and as far as I know there were no updates or changes.
Any ideas or suggestions?
