There's no web version of element X though? It's what I use most of the time. I'll try the Android app anyway, I've been having a really annoying bug with the normal one anyway that hasn't been fixed for a year. So perhaps X doesn't have it.
Element X works pretty well on macOS as a desktop client if you have an Apple Silicon Mac. Otherwise, the big Element Web rework is yet to happen. On Android, I can almost guarantee your bug will be fixed: Element X Android doesn’t share any code with Element Android at all, as far as I know (given the former is mainly written in Rust, and the latter is all Kotlin)
Getting a let's encrypt cert is very difficult because my server can't get reached from the public internet. I have it that way because I use this one only for bridging and I'd like to keep it safe.
