I too am having a similar problem after latest update. I have the PC version from the Microsoft store. With say the C172 or the Beechraft Baron , moving the flaps with F5 to F8 keys, the flaps move as expected but then reset themselves to the “1” position. I dare say other aircraft behave in the same way. I have checked all bindings and there are no defintions of flap movement except for the keys mentioned above. Even moving the flap lever with the mouse shows the same behaviour. The flaps worked perfectly before the update! I do use FSUIPC7 for most control but have removed this for my checks. Any suggestions? I have completely uninstalled MSFS before to rectify problems, but this is a long process and I would like to avoid having to do this!
