I tried using qBitTorrent after doing a clean install of 20.04. When I ran a test search, it returned an error. I tried turning all permissions on and that made no difference. Since I still have a 19.10 install on another computer I confirmed qBitTorren works there using the regular install. I then tried the snap install. Same network issue as on 20.04. I added the qBitTorrent repository to apt and downloaded direct. That version works fine. (It also starts much more quickly and seems snappier. Pun intended, of course!)
I'm running 19.10 with MATE desktop. Since the last update, the picture on the "bing.com" web page doesn't show up in chrome. I have a second PC running 19.10 that had the pic show up, updated, and it disappeared. My google-foo is not strong since I found no way to submit a bug report and didn't find anyone else had this problem. It's certainly not a big deal, but weird.
When I try to login to audible on Chrome it always says "time out". It works on Firefox so I have a workaround, but FireFox just doesn't usually work for me other than in this case.
Evolution appears to not be able to connect to Yahoo email. It prompts for the password, and keeps doing so after every attempt. I have Thunderbird working with it so I know it can work! I have two-factor on, but turning that off made no difference. No error messages are giving, it just keeps prompting for the password and not working.
