This losing controller profiles and then having to lose the whole profile (hrs, achievements, controller etc) I had my third event of this, and still no fix.
[Fix Controller profiles (Missing or Corrupting) - Bug Reporting Hub / Miscellaneous - Microsoft Flight Simulator Forums](Fix Controller profiles (Missing or Corrupting))
Have to say unsure what the reply was, other than Jorg will look into it. But seems to get impression they said Xbox issue, no idea about Xbox but for sure problem with PC, and not because MSFS crashes, happened to me with normal shutdowns and normal next starts.
But why no real answer!
Please Jorg and team, can’t you have a good view of questions (planned) well before so a meaningful answer could be given.
