I have just left the SU14 Beta and now I have to install SU14 again plus all the content I have previously uninstalled (like airports/discovery flights/bush flights/liveries/aircraft etc) Its all getting reinstalled! So i have to sit here for hours while it downloads and reinstalls 56GB of ■■■■ I don’t want.
How do I stop this happening please?
Is your simulator on a custom path? 
Yes
D:\Microsoft Flight Simulator 2020
You don’t need to unenroll after a beta flight if you are going to join the next flight, if you stay enrolled in the beta then you will automatically receive new flights as they come out 
I am aware however i might not want to join the next flight so thats why i unenrolled. I’d rather choose, than have it forced upon me.
So is this normal behaviour, having it reinstall everything again once unenrolling?
