History Glide

Someone who has access to my Glide account made a huge mistake and I now need to re-do a lot of my app structure.
My whole app is built around a welcome page. When you click on one tile, I have an inline list and then I personalize my pages like that. He changed the source of my welcome page and now all of my personalization is gone.
Is there a way to revert in history ?

Thanks !

Once you leave the editor. There no way about it. Sorry to hear that.

Did you use individual configuration for the tiles?
