Due to a bug in the software, inviting new accounts with upper case letters is currently not possible. Therefore, please use only lowercase letters in the email addresses for which no account exists yet and which you invite as a guest.
In order to stably provide the service, the Circles app is deactivated. All users who use Circles with groups of users can therefore not use this function right now.
The functionalities of the Circles app caused numerous very time-consuming queries in the database cluster. These endangered the service as a whole, so the app now had to be disabled. We are working with the manufacturer of the software on a solution to make Circles and the relevant functionalities available again in a cleaned-up form.
As of January 2022, only clients from 3.3 can access the service.
