Teams Sidecar issue

[whuzzle]

I have a query with Teams Phone - running a Yealink MP56 with an EXP50 connected to provide sidecar functionality.

I'm having an issue on a few phones where the pinned contacts on the sidebar have blank names. The Teams icon is there, the presence indicator is correct, but there is literally no writing in the space where you'd expect the name of the contact to appear. Has anyone else seen this?

Patch levels for the devices are up to date as far as Teams Admin Center and Yealink indicate:

MP56

• Firmware Version: 122.15.0.77
• Hardware Version: 122.2.0.0.1.0.32
• Company Portal Version: 5.0.5304.0
• Teams Version 1449/1.0.94.2022030501

EXP50
