Don't use the app; syncing to Android works fine, but not the other way around. I've experienced issues, such as invisible text and deleted notes not disappearing.

The default theme has contrast issues now as well with note preview text hardly unreadable.

I also don't see a reason to show the title in the actual note when it's already shown at the top.

It's a good effort, but could use some improvements and features such as:
- Search
- Sorting by title or timestamp

My previous review was about how nice and simple this is, and how I did not want fancy formatting etc That is still true, but I now have a complaint. So, I want to use this briefly once every few days, usually to transfer some text from Android phone to laptop where Firefox is running all the time,l sometimes the other way round. EVERY TIME I now find the Android Notes throwing up a screen how I have to log back into my Mozilla Account, a screen for user name, a screen for password, then a wait for an email (except I always get two identical ones for no reason), have to open the email and click on a link, then wait for and click through the OK screen before FINALLY the Android Notes will Sync. Why? No - WHY? Same laptop PC, same phone, both running Firefox for a chunk of the day. THEY don't insist I have to log back in every time I start them up, so why does Android Notes? It is INFURIATING and makes other what I thought of as long-winded methods of transferring some text between laptop and phone actually quicker and less involved than using Notes. PLEASE do something about this.
And then when I'm logged in, I appear to haev to manually sync the Android notes after each new note or deleted note, which I'm sure I didn't used to have to do.
