Hi… the reason why deletion of rolling.cache is recommended is, that you get a clean / fresh rolling.cache file - without possible data issues. If you have in-game the rolling.cache enabled, then MSFS automaticly re-create a new ‘clean’ cache file if you removed the rolling.cache manually 
Dont !! remove the file while the game is running. Stop MSFS, remove the file, start MSFS - then test whether the issue goes away. Or alternative, do all the rolling.cahe stuff only from the in-game settings menu, where you can enable/disable and also remove the cache.
If you still get issue after you removed one-time the rolling-cache file, then the reason for your problem is not the rolling.cache.
Regarding Cloud-Save ( I missed your post ):
You own also the Steam version and not the MS-Store version, Right ? If so, then you pickup the wrong FAQ regarding cleanup cloud-save.
The newest post I wrote about Steam-Cloud-Data is here, may be its more helpfull
PS:: and to be sure… you never had installed e.g. the google-map-replacement mod ?
