Hello everyone.
Please tell me how I can watch and download videos using F-droid applications now?
I checked several:
NewPipe does not work
LibreTube does not work
SkyTube does not work and I also have the screen backlight involuntarily turning on at 100%)) apparently a bug…
I get the message:
Got error: “Sign into to confirm that you’re not a bot”
works for me
Did you try to not be a bot? 
Do you use a VPN or Tor?
LibreTube works for me see this TWIF : Voice your updates | F-Droid - Free and Open Source Android App Repository
For download ofc Seal as yt-dlp client is the best
$ yt-dlp -f 'bestvideo[ext=mp4]+bestaudio[ext=m4a]/mp4' 7FfWz1NRQJQ

I tried double VPN and triple VPN it doesn’t work!
how about NO VPN?
Good sense of humor))
I’ve asked:
Do you use a VPN or Tor?
You answer:
I tried double VPN and triple VPN it doesn’t work!
I don’t know what you have…
if you don’t use a VPN … just say that.
If you don’t use a VPN… cry to Google or your ISP or or or
you didn’t understand what I mean, the problem is not in the VPN, read [Bug] "This helps protect our community." - "Please sign in to confirm you’re not a bot" · Issue #4734 · iv-org/invidious · GitHub
Can you record a video and show that NewPipe is working for you?
Newpipe works fine for me too.
Can you record a video and show that NewPipe is working for you?
Nobody (including you) lying here, showing screen-recorded video as proof won’t help anyone.

I always lie
@bob.fg – if seal isn’t working for some reason (although it looks very good), have you looked into using yt-dlp via termux on your phone? I haven’t tried it, but yt-dlp is very good on desktop.
There’s also clipious. I don’t watch a lot on the phone, but it worked very smoothly the few times I’ve tried it. I don’t know if they’ve downloads, but it was all very well done, so worth a look perhaps.
Invidious: they have historically always found ways to work around the crap youtube (aka google) throws at them. You could always try the tried and true method of all tech connoisseurs: do nothing and wait until the issue resolves itself.
Lastly: why download videos on the phone? If you’re at home, you probably have a computer where you can watch them. And if you’re out and about with only your phone, do you really want to be that guy staring at his phone on the bus? Get a book from the library, or take up doodling 
It’s not that you’re cheating or not, I just asked you to show it, because it doesn’t work for many users (read reddit), it doesn’t work for me either, and the problem is not in the VPN or Proxy, but in the fact that YouTube (Google) changed its policy for users.
I gave a link where the developer of invidious also reports this problem.
The Invidious team is aware of this issue. It appears that it affects all the software using YouTube.
As for my request, there is nothing special here, if you, for example, report here on the forum that some program doesn’t work for you, then you are asked to show the problematic one.

You gave a link to a developer of invidious making a comment two months ago about a problem which may be tangentially related to your problem. Invidious are constantly in a cat-and-mouse game with youtube, so it really means very little now.
And now when three people told you that they were watching and downloading videos variously using Newpipe, LibreTube, and Seal, you proceeded to not take that datapoint seriously.
If it’s working for those people, the problem is probably something else on your side. Them showing you a video would change nothing.
Actually, make it four people. I just installed Newpipe and downloaded some silly video of Gordon Ramsey that showed up. It worked immediately with no issue. I will not be sending you a video of the process.
Absolutely. You’ve got to fight their diagnostic mental health criteria and DMCA intellectual property protections. You need a court psychiatrist and a heavy-duty pro-hobbyist pro-bono law firm for that.
