I've not been able to edit posts on Android since August 2017
I was also concerned to read elsewhere in this forum that you still haven't even confirmed the root cause of the problem yet, but you "think it might be something to do with non-standard Android Keyboards".
Given I use the default Android keyboard, that suggests to me Wix haven't identified so much as the root cause of the problem, let alone found a fix.
Isn't it time Wix handed this bug over to someone who can actually fix it? I've had over a year of stock responses like "we're working on it" , "it's fixed" (it actually wasn't, this was untrue), or "we can't reperform it"
