We are aware that individual community apps won't load on iOS / iPadOS 13.
We are now offering a new 'Fandom app' that contains all the same content you see in these community apps, along with additional features (such as light and dark modes) and articles from other wikis.
We strongly recommend that you switch to that app since we're no longer adding improvements or fixing bugs in our community apps (and this includes iOS / iPadOS 13 compatibility fixes).
You can read about the new app on this help page, and you can download it here:
Thanks for using our apps!
