I just migrated from iMac to a Mac mini and downloaded the latest version. The version is 7.0.0 on Sequioa 15.4. I am sure Google/Alphabet must have tinkered with video settings because I could download videos Friday. Today, Sunday, I get the dreaded error message stating I should right-click and get the URL (I did...). Please update the Tools to reactivate video downloads. This is my main use.
