I have created a report and shared it to several users. When anyone else tries to open this report, Power BI just starts loading indefinitly without any error message. Currently the data model contains no roles, so I don't think this is a data related problem.
Any suggestions what could be the reason for this behaviour.
all users have a Power BI Pro License. So that's not the problem. However I will test what happens when the users open PBI directly and try to open the report from shared reports without using the direct link.
