Always useful to be getting paid - especially just before a super-long bank holiday weekend!
If you’ve not already done so I would reopen the case with Customer Services - this is definitely a Starling issue - they need to look at this again. My guess, for what it’s worth, is this is associated with the clever shenanigans that go on behind the scenes to provide enhanced metadata to the app experience (things like a nicely formatted business name, map, and graphical logo). Sometimes things get a little messed up - hardly surprising given the complexity. I am sure this is fixable. But don’t let them fob you off.
Maybe someone like @Patrick could step in and help…?
