Hi @dannymohammad, I didn’t do an exhaustive test on different file types. I tried a text file and an excel file. Both showed the same problem. One thing I forgot to mention, is that I tried it with Chrome and the desktop client, both got the white screen and had to reload to recover. Even after reloading the issue persisted. I even cleared the cache and reloaded and still had the same issue. I also uninstalled and reinstalled the desktop 4.2 client to see if that helped which It didn’t.
Weirdly enough, I believe it worked okay with Microsoft’s Edge browser. I didn’t have time to do a lot of testing before I rolled back to 5.5. I didn’t get a chance to try it with Firefox.
