Which I'm going to freely say was a mistake. Everything worked with 12. 15 has been nothing but a hassle since we bought it.
Dear Teamviewer stop trying to cram every feature under the sun into your product and stick to the basics that made us buy your product in the first place.
So with that said, The users are registered under company users but their license refuses to update. So every time they start the program they get the "BUY ME NOW" pop-up.
And it's not all the users it's only a few of them.
I opened a ticket with TV support, the support person looked at the issue, said "That shouldn't be happening" and I haven't heard back from him since.
I'm to the point that I am going uninstall 15 and go back to 12.
