Typing glitch
I’ve never used any of the plugins you mentioned and I’m having issues too, I was thinking maybe it has to do with Android: Long-pressing items in sidebar views / tabs more than once makes the app freeze (about Webview implementation) but then I disabled everything, restarted and tried in restricted mode and still happens what’s showed in the 2 videos/gifs.

Before that I was noticing that the live preview was taking to much time to “render“. Example, I was typing in a H2 heading and the test didn’t changed correctly, only after some time I showed with the style of a heading.
@jacksback24 I would appreciate you confirming if this is the sort of problem you are having too.
Additionally, the output from '“Show debug info command“ may be helpful.
