Pi Zero W with Buster
iPad OS 13.3
when I try to creat a trigger (in this case for DS18B20 temperature sensor) the panel allowing me to set the trigger parameters does not appear. When I do this on my iPhone it works and I can create triggers that work.
Mysteriously this has now fixed itself!
Whether it was because I tried to access the web dashboard from my iPad (which you cannot, it just links you to the app) I cannot know.
However, all now fine.
