On the bright side, this issue finally got me to create a forum account. Experiencing this as well on my iPhone using iPhone/iPad/Mac. It might also be occurring on my iPad but I don’t use the toolbar there so I wouldn’t notice.
It’s fairly frustrating, obviously UI is a little tricky on the phone and the mobile bar is a great compromise. I rely on it heavily and spend a lot of time picking and arranging my actions. For example, since I can’t set a default new note templates without learning Javascript or messing up my Daily Note, Insert Template is usually my first action. It’s already more taps than I would like, but it works well enough to get me writing.
Disabling settings sync would be difficult, not having to think about different configurations is why I started paying for Obsidian. I hope this gets figured out, I don’t prefer working on my phone but it’s the device I always have on me so this feature is important.
