It bugs me so much now that I will just leave it here. For me mobile is close to unusable. And always has been. I use android with chrome. when I try to edit anything in a written text or try to delete it or try to select it or do anything with an already written text, no matter is new or an edit, the selected word or letter or entire sentence gets randomly duplicated and sometimes positioned at a radom position in the text. It also sometimes randomly does not save some parts of texts or after a saved edit suddenly the same text is there twice. In the past I have written texts sometimes on a textapp before to just paste it directly, but now I just really try to avoid spectrum on mobile as much as I can. It is really bad and I am surprised it has not long ago been fixed. I guess it is only me? Oddly though I have it on three different android/chrome devices, so I would have thought I am not the only one.
