Hi all, hope all is well.

I have two customers using the SL3 Compact OVHD panel (with the RP2040 SMD controller). After they installed the latest beta 11.1.0.5 the device mappings are all messed up, like they have new assignments. Seems like register remapping or something? Can anyone shed some light? I guess the only fix I can ask them to do is revert back to the official stable version.

Thanks!
Santi

It's a known problem with the shift registers in the new firmware. If you go back to official and reinstall the firmware it'll fix it

They'll need to reinstall the firmware once they roll back to the earlier version of MobiFlight
