Partner chat text not displaying

[zmin]

Hello,

While chatting with a partner both using version 10 of Team Viewer, I've been noticed that none of the text my partner writes back is displayed on my screen.

Both computers are under the same account, both are set up for unattended access.

This is a recurring issue, the last workaround was updating both client versions (using free license), but now they are both up to date. Any fix for this please?
