Is there a way to stop discord from messing with my UI?

I use android mobile app and browser version.  Is there a way to reverse the UI changes on both, and prevent all future UI changes?  I do not want discord to decide one day to change my font or move buttons around or remove them.  Also I don't want to have to switch from the browser version to the desktop app.  I just want to keep my familiar, semi-functioning, well-styled experience, as if nothing happened.  I don't want to look at some corporate redesigns and pretending-to-be-useful nonsense where they shuffle things around and recolor them.  Leave my shit alone.  

For browser version, betterdiscord was the first option I was interested in, but it seems to be only made for the desktop app version.  I looked at vencord which does have a browser version, but it seems to have almost no content, and doesnt have the older UI.    

For android version I tried downloading older versions of the discord app.  I was able to install a Nov28 version but it had the new UI.   I seem to be unable to install the Nov21 version because it says “App not installed as package appears to be invalid.”  I am currently trying to get around that issue and see if Nov21 has the new UI as well.  I'm not sure what version added the mobile UI.  I also disabled automatic updates for my phone now, so maybe future UI changes won't be applied to the mobile version.  But I want to remove the current change too.  

If anyone has any tips or help then that would be appreciated.  

Fire the people in charge of discord.  All their updates lately have been useless UI changes that are nuisances, they've been shuffling around and recoloring for years, and adding random sparklies whose only purpose is to add soulless corporate flair for people who spend a billion dollars, expecting this to bring in more money.  The app has had functionality issues forever, and they aren't being addressed.  The company is getting more and more desperate for nitro payments, so they seem to be doing financially bad as well.  Also I saw a video about how the staff are being treated miserably.  Whoever is in charge of discord, they must be terrible at their job.  Nobody should rehire them after the company goes bankrupt.
