Hi @Aa-ron! Thank you for a quick response.
While trying uploading different files to different services to test some more and understand what could cause the problem, I found out the actual problem was not with file extension or the service I’m uploading to, but it seems to be something about the file names. I can’t upload files that have Cyrillic symbols in names.
What do I do in this situation?
I tried uploading files with Cyrillic symbols with Firefox 81.0 and there was no problem, so I guess it’s not about my system.
Also, should I update my original post with the info I just wrote?
