Kdeconnect can't connect to my ios device after the last update

After the last update, the kdeconnect is updated to version 23.04.0-1. I find I can’t connect to my ios kdeconnect app any more, both on iphone and ipad.

When I try to use the app to connect to my PC, it seems that the connection is established for a very short time and disconnecting at once. I have tried to reinstall both the app in my PC and in my phone, as well as repairing two devices. But nothing works. Even if I downgrade the kdeconnect to an older version, I still can’t connect two devices.

Any ideas?
