New Interconnectivity stopped working

[markus.]

Hello, I have a 13 Pro and a Pad 5 Pro 12.4.

Yesterday I installed the stable xiaomi.eu Harmony OS ROM with fastboot on the 13 Pro (beforehand I had xiaomi.eu miui 14). Current Version: 1.0.5.0.UMBCNXM

The Pad 5 Pro has the original chinese ROM. Version: 1.0.1.0ULZCNXM

Yesterday I was stunned by the interconnectivity display sharing feature after installing the update on my 13 pro. But out of nowhere today when I tried to share my phone screen to my tablet again, it didn't work anymore with the error "This device's system has been tampered with. Can't connect due to security risks." (Screenshots)

But the other interconnectivity features still work (e.g. sharing the gallery of my phone to my tablet)

To me this really doesn't make much sense as nothing has changed over the night. Restart on both devices didn't change it.


thanks in advance for helpful replies

The same thing. I had Xiaomi 13 ultra with eu rom and Xiaomi pad 6 pro china rom plus magisk and root. Anyone know how to fix it?
