This might be the same as element-hq/element-x-ios#3055 which was fixed by matrix-org/matrix-rust-sdk#3964. I'll leave this open as well until there's a EX-Android release confirming this.

Same here with 0.5.3 ex android.

It took hours, then messages got decrypted.

I see this has been fixed on the SDK. Should this be closed?

[poljar]

I think people leave the app issue open until a release happened with the updated SDK.
