I’m having the same issue, iPhone 12, iOS 17.6.1, mastodon account @halfflat@assemblag.es. It doesn’t even crash, just loads the splash screen and gets stuck forever which is pretty odd behavior on iOS.

Hi! Sorry about that experience. It seems we have issues with some specific Mastodon instances due to a bug in one of our Mastodon libraries. We fixed that and we will release the new version soon 🙏
