So it looks like that TeamViewer has joined the trend of not allowing contact anymore.
The Contact Us link, brings to a "Submit Ticket" button that sends back to the community. This is not a Support ticket. No way to contact them anymore. The former email address is gone "to improve your user's experience". Obviously.
When businesses don't understand that cutting themselves from their base, the customers, is the worst way to do business.
Now they're going to say "we don't block you from contacting us, we have an open community, for you to speak out". No! The community is not a direct contact with the company.
Even posting on the community is a hurdle: please correct the highlighted fields. There are NO highlighted fields.
Moving to another product.
