On a couple of instances, the Calendar comes completely empty for my user. Both the global one and the program focus. The very weird thing is that it's apparently user related: for a given user, it happens on all browsers on multiple devices, but I can connect on other instances on which, with the same browser, it works perfectly fine, and other users on the same instance do not have the problem.
I have already asked support for this issue, and they never came back with an answer, saying they cannot replicate the issue (obvisously...)
Has anyone faced this issue ? Any hint ?
