I have the same problem. Takes ages to gen anything done like this.

Hello Lilli Hantke ,

Please make sure that the internet connection is stable and try to use Chrome browser.

Hope this can help you.

Thank you for having put your question as it provoked an answer. So far I've been working on a laptop (because it works on that) but the online editor still refuses to work on the desktop. I shall try this chrome browser suggestion and see what happens.

I am using chrome unfortunately. Never got the editor to work on any other browser in the first place. 

I am also working on laptop and having this issue. let me know if it works with chrome although I am already using chrome

 Lilli Hantke Can you please tell me on what file format you are working?

It's a word file (doc.). A project assigned to me through TRADOS Studio.

Another thing that suddenly happens frequently is that I am calling up concordance search with fn F3 and suddenly everything apart from the green header disappears and doesn't come back. Where can I report bugs? I have a deadline and am not able to finish the project like this. 

Ana-Maria Matefi  there are a number of other issues that are also annoying but not as hindering: When I try to open the concordance search vie fn F3 the page gets white (like it is loading) with only the green banner on top but nothing ever happens. I am losing where i was in the segments and have to reload the page. When I want to insert a comment and click on the icon in the right bar, the bar disappears and again I have to reload the page. It really has been a pain for the last 4 days or so. is there anywhere I can report these bugs and maybe send a video of these things to?

Hi Lilli, I did some updates on my PC and now it's working on Microsoft Edge but still not on Firefox.
