Problem downloading files on whatsapp web

I searched and found no related post.
I use whatsapp web with a bussines account on a fixed tab on vivaldi. If I have to download files from wathsappI have to download one filethen reload the webpage to download a second file. If I don't do thatI see a message "file downloaded" as if the file was really downloaded but nothe file was not downloaded.
This happened with different vivaldi versionswith different whatsapp web versions and in windows 10.
Have been this reported before? Is there any way to fix this?
