I thought so too.
Well, but unfortunately it happened.
I read somewhere that if a file was already originally installed in the Community MSFS folder, it cannot be moved “with impunity”.
The only method is supposedly to reinstall the zip files in the new MSFS Addons Linker folders.
I would love to be wrong and have someone tell me what I can do to avoid tedious downloading and reinstalling scenery / airports / planes etc.
