new version on phone

Please, mojang, bring back the old classic control buttons (I'm talking about running, jumping, etc.).
It is very inconvenient to play, even impossible, I would say. 
and also, not knowing that Minecraft was updated again, I deleted it and downloaded it again due to account problems.
and now I can't log into the cube craft  server because the server doesn't support the new version.
how long do I have to wait ???
and please i tell you again, return the old control buttons PLEASE, I BEG YOU, I CAN'T PLAY WITH THE NEW ONES

v 1.20.81
