There are quite a few issues that they've stopped fixing in the Element app in favor of doing it in Element X, the one I've been following is where the iOS app causes a breakage in E2EE when you use the share extension, so they just disabled the share extension entirely and said they'd fix in X - https://github.com/vector-im/element-ios/issues/7618 https://github.com/vector-im/element-ios/issues/7618 But X requires Sliding Sync on the server, which is still a separate service to run alongside the homeserver and doesn't have a stable API. I am increasingly disappointed with how centralized Matrix is becoming, since AFAIK there isn't really an alternate client close to the same level of quality as Element. I probably would've made all of the same decisions myself though, so I don't blame them I'm just a bit disappointed in how it's shaking out.
