#2790 - Invalid server answer when i set the new account in calendar
I have installed activity sync in the crm of a client of mine and activated the license correctly. When i set the new account in my Android mobile calendar i get the following error: "Invalid server answer, check URL". I have followed the instructions but i can't connect , also another member of my team tried with an i phone but he get the same error. The crm version is 7.6.6 while the PHP version installed in the server is 7.0 Could it be a version problem?
Thanks in advance for the support.
