Thank you very much for your response. As much as I would like to believe that the Android app hasn’t been “abandoned”, I see that the last update was in October 2021. That being said, there are issues (including the ones I’ve mentioned) that have been going on since before the last update. Almost a year later, they still remain unresolved (see Android annotations disappear on Samsung tablet, Transparent Paper Title in Android Tablet Version). Annotations might be tricky to solve, I agree, but changing the title styles seems to be a trivial fix that should not take months.
I don’t intend to undermine the efforts that the team has put in to make a product that I would love to use everyday, but my point remains that there needs to be constant effort in making sure that things run smoothly. I really hope that this gets taken care of.
