1.4.2 Cross-Signing "The MSK is missing..."

Just updated my mobile and tablet to Element-ios 1.4.2.
In Settings > Security > Cross-Signing I now have a ⚠️ sign saying "The MSK is missing. Verify this device again or .."
This message was not present before the update.

All 4 of my devices are still displayed as verified in all clients (mobile&web) and Cross-Signing is active and I have green shields everywhere. Has to be a bug?


Contrary to whats written in the screenshot there is also no option below or anywhere else to "synchronise my keys" nor any way to re-verify this session/device from element-web as it is already trusted.
Secure Backup is active AND has a valid signature from verified session Mobile AND Tablet, which are the 2 devices showing the "MSK missing" error.
