Hey all, we have a known issue with pages and reusable elements that were deleted a long time ago reappearing in users apps. This is a one-time problem that occurred on Monday. We believe it should only affect a small number of apps, but I wanted to post about it so that if your app is affected, you know how to handle it.
Basically, what happened is that we used to have two separate lists of all the apps and reusable elements; a big list that contained all the data, and a smaller list with just the names, which we used to quickly generate the page dropdown in the editor. This system was buggy, and the two lists sometimes got out of sync with each other, which caused a lot of issues. On Monday, we replaced it with a new system that automatically regenerates the small list from the big list in a way that makes it much harder for them to get out of sync.
However, certain apps had pages that were deleted from the small list but not the big list. This made it look like the page was deleted, but the app was still storing the data. Because of our change, the small list is now accurate again, and the pages are now showing up.
If this happens to you, it’s safe to just re-delete the page or reusable element that appeared. This is a one-time issue that occurred because of the transition to the new system, which will hopefully be much more reliable going forward.
Really sorry for the inconvenience.
