Hi Mirek,
my previous question was not answered but I could not continue the thread :-(
So here again my question with more input!
I am encountering issues when having renewed licences for add-ons within our Jira instance.
I go to manage add-ons and expand the according add-on details, the details expand shortly, approximately 3 seconds and then collaps again. With this I cannot enter the new license purchased.
This behaviour is consistent over all add-ons in the menu and with all browsers used!
Any ideas?
