Sorry for the delay, but I installed the v1.64b1 from F-Droid, and everything works as it should. Thanks a lot ! Oh and BTW, I wouldn't blame you if you decided to stop supporting Android 7.0. It's an old version. I just hope the last working for 7.0 would still be available, that's all :)
Good catch, but no dice. I'll try again a bit later, but I think, for the time being, that I can't give you the feedback you need : I successfully reinstalled the app from F-Droid, uninstalled again, checked in /data/app and /data/user/0 for the presence of the "gho" string, and nothing. cmd package list packages -u | grep gho (as root) gave me nothing too, with of without the --user 0 at the end of the cmd command. And all that, still with the same error I'm at a loss. So, I'm sorry, but I'll put...
Sorry, I wasn't clear : yeah, I did that. I uninstalled it, rebooted, removed the app folders from /data/user/0/, but at each steps, when I tried to install the new version, it said that. It's probably not your fault at all, I just mentioned it to make sure you'd know that I wasn't ghosting you, I just can't give you feedback right now :)
I don't seem able to install that version, because I don't seem able to remove properly the previous one (I get "A package with the same name already present"). Might be an issue on my side, I'll try again later. Note : I forgot to say this, but I used the F-Droid version. It might be interesting to know that I haven't chosen to install the beta version, but it did anyway. I don't know if you are the one handling this, but just in case, a FYI :)
