Purchasing Version 11
I bought team viewer in July of 2016. I paid almost $1,500.00.
A few month later you come out with version 12 and I have to pay almost $600 to get an upgrade. This is not fair.
Had I known that you have a new version I would have waited. Since I don't use it much anyway, this would have been not problem.
I am using it to troubleshoot customer computers. Since you always prompt to "upgrade your version now" ... my customers do that and then they are stuck with version 12 and I can no longer access them because I am on version 11.
If you come up with such a shady schema, then at least give me the ability to lock my customers from upgrading.
Every software I ever bought gave at least half if not even one year of free upgrades, after on the purchase date.
Shame on you TeamViewer!
