Hello.
Thanks for something so useful.
Environment is Windows 10, Firefox94, Tampermonkey4.13.6136

--------------------------------------------------------------------------
Question1.

Youtube polymer engine fixes is the default setting.
But the list of videos on a particular page is not displayed
There are two pages that are not displayed.
Official YouTube news and live channels.

Can this be seen in the settings?
Or is it the environment?
I added news and live to exclude and it shows up fine!

Question2.

Seems to conflict with Youtube polymer engine fixes.
The add-on will not work unless you turn off Youtube polymer engine fixes on the channel video page
Added channel video page to exclude
But the page is not excluded
Is the regular expression wrong?
I would like to know the cause, please advise.

Q1 will investigate.

Q2: that's probably because YT likes to change page without actually loading them (more (here)[https://developer.mozilla.org/en-US/docs/Web/API/History_API]). All script managers load scripts at page loading. They can't unload script when URL changes without page reload.

Does problem persist if you disable all options for YTPEF?

Nice to meet you Bogudan!
Thank you for your quick reply.

I think Question 1 is due to my environment since you guys have not reported any problems!
thank you for your trouble

Question 2 was not resolved by disabling all options in YTPEF
So it could be due to YouTube's page loading specs.
I can't seem to help myself.
Youtube polymer engine fixes can't be removed by any means, so I'm giving up on the add-on.

Thank you for using your valuable time.

Q1.

Fixed for YT channel in 2.22.1.

News channel does not work even without YTPEF :( Probably it's regional thing because without proxy I get empty page, with proxy -- header with tabs (top stories, storts, etc.) but tabs are empty.

Q2: Addon in question conflicts with setting "Channel/Set thumbnails width". Setting it to "default" should fix the issue.

Also, #? part is added by addon.
