I went on my Forza Gallery a couple days ago and everything, and I mean EVERYTHING has been deleted except for Forza Horizon 4 pictures.
Anyone else have this problem?
If so… WHY DIDN’T THEY WARN ANYONE?!
Click the Gallery menu link and you get this url:
https://www.forzamotorsport.net/en-us/gallery/dR3K0b?title=FH4
What do you see when you manually change it to this url?
https://www.forzamotorsport.net/en-us/gallery/dR3K0b?title=FM7
Thank you sooooooo much!! It works with all Forza pictures by changing the last characters of the URL to other Forza games. 
Much appreciated!
