If you use Freetube, you haven’t failed to notice that Google is on the war path again and broke it a few days ago. See this bug report.
Please note that it’s been fixed in this PR. If you download the nightly build #5652, it now works like a champ.
Thanks team Freetube!
Google clearly has the ability to break any and all third party client at any time.
My theory is that they’re conducting random campaigns of working-but-not-all-the-time on this or that client at different times to grind everybody down and force them to comply through shear exhaustion. Because if they banned all 3rd party client outright, it would negatively impact the antitrust case against them.
