Unfortunately writing just to say “me too”.
My experience on several devices trying to visit Main UI of OH3.2.0 build #2520 and just updated to #2546 RPI4 (manual installation):
- on RPI4 itself:
Chromium: NOK
Firefox: OK - on wall mounted tablet Teclast P80h:
Fully Kiosk: OK but slooooow
Standard Browser: OK but slow - on wall mounted tabled TYD-108H:
Fully Kiosk: NOK
Standard Browser: NOK
Firefox: OK - phone Samsung Z Fold 3
Samsung browser: OK
Firefox seems to be the best working across devices.
I hope these info help.
