What @Peter_W said.
But if it still doesn’t work, it may be because your TV is just badged Sharp, and is actually made by UMC, and needs a UMC code for the remote, not a Sharp one.
If this is the situation, it is something the automatic TV recognition on the Boxes Pro and Mini cannot cope with 😢
So you can either live with it, or source an earlier YouView remote (any one will do, though my choice would be the original curvy one for maximum flexibility), where you can try the codes for UMC, and maybe one of those will work.

and select Remote Control Code List.
Or a One For All remote can be similarly versatile.
It does mean you will lose the Bluetooth option, and go back to needing line of sight with IR, though.
