I've had the same problem for over a year. I can only edit from laptop. It is really time-consuming to have to keep switching to laptop to update my lists' notes since I have to update in bulk now rather than on the spot.
I've tried the android internet browser, the chrome and brave browser. Nothing works. Desktop mode doesn't work. Further, I can't even do many types of editing on my mobile/tablet like filling a table with colour. Have to use a laptop. Can't select quote on mobile.
It's really sad these features are not available.
