Additional meeting and call-related features and issues within Microsoft Teams for business
I have the same issue and having multiple users reporting this issue. We are on Microsoft Teams version 1.6.00.376 (64-bit).
Jabra models (which are all up to date - both headset and dongles):
Jabra Engage 75
Jabra Evolve 65
Jabra Evolve2 65
Temp workaround is to go into Teams settings > Devices and the do a test call > leave the phone call and the presence should reset.
This same thing is happening to me as well .. both Jabra Evolve 65 and 75e models.
Your work around works, but would be nice if the problem was fixed properly.
