I read through this topic and I think we should close this topic for several reasons:
- the initial problem has been solved very quickly but people continued to post whatever problem they had with collabora and nextcloud.
- a lot of these problems have also found their way in tutorial and documentation improvements
- it is extremely difficult to keep track of individual problem if everything is mixed up (and for people having a similar problem to find out what finally solved this problem)
This does not mean that there are no problems or everything has been solved. For new problems open new topics. If you follow up an existing discussion, your problem and symptoms have to match the original post.
