Crikey! Erm, I think I’ll wait for the bug fix. One further question, if I may, can I go ahead and add all my non Hornby sound chips (as additional locos associated to the Dongle)? The ability to customise the F icons in the TXS app is BRILLIANT, as it’s a real pain to try and remember all their individual different function maps. The ability to customise each loco with its own individual icons for function maps is a massive benefit. What I don’t want to happen is do all that work (30+ individual maps) then find that data has been lost in an App fix/update?
