Describe the feature you want

Currently in what's new when we refresh the whole UI is basically blocking by loading screen. In my opinion this is bad design as there is defot no need for blocking user from watching videos or browsing channels etc while new videos are loading.

So my suggestion is removing the blocking loading screen and leave the notification for that purpose as notification shows us how many videos are being fetched.

Is your feature request related to a problem? Please describe it

Additional context

How will you/everyone benefit from this feature?

People will be able browse videos, watch them and use the app while loading new videos.This is not the case currently.

Ii created a often updated group so i can update on channels that upload often, like maybe 5-10 subscriptions and then after, i update all

But updating all also blocks often updated, even if those feeds where just updated 1sec ago :(

I came by the same Issue from adding FeedGroups as avialable Tabs for the main page.
Currently there is only one static Progress Status tracked internally.
I have some local hacky solution to prevent it showing up on unrelated feeds allready.
I don't think it is good tho, which is why I created #12336.
I'd prefer to create a good internal infrastructure, which could also enable more fine grained UI stuff or potentially track parallel progresses.

I don't have a concept change so far, I'll leave it a kind of open discussion atm.

Kinda unrelated, but ill share my "workaround" around blocking UI while updating feed

Playlists arent blocked, so now I purposely have a playlist with pending videos. So I always start there while waiting for the feeds to update :)

It does nothing to fix this, but with this flow i dont have this problem anymore :)
