The US dropped from 4.9 to 4.8 but is still the highest rated email app in the Play Store. As many have said in hear before the over all rating really doesn't mean that much especially when less then a .1 difference and when there is no other app even closer to reaching the reviews or rating of this app.Not all reviews have a text, and therefore not all ratings are visible. The average Play store rating calculated by Google has been going down only the past months, with a few days with an upward blip.
Anyway, circumstances force me to reduce the time I am spending on this project anyhow, which means that fixing bugs will be prioritized, with little room for new features. I might take on some challenges as a distraction, though.
I understand the need to focus on personal life. Health, mental health, family etc are more important. As I have suggested before it would be wise to not be the only one handling everything related to the projector. It would be less stressful to allow members of the community to respond to complaints or issues.
I'm also concerned who will manage or maintain this app once for whatever reason you can't. I don't have the computer power or the programming skills to help with development (I wish I did) but I do have front end skills and time to respond to complaints and emails. Just something to think about again.
