Updated to 3.01 HX Stomp version like other people here, I lost my main custom presets with split A/B cabs.
The splits were odds after update (screen 1 below) and modifications (screenshot 2) were not saved , then after few trys deleted.
Presets then does not have sounds anymore or cannot be edited or are deleted...
Screen 2
And on the pedalboard footswitch configuration are blank (and should not be)...
Cant believe this mess... So disappointing!
