• closes [Feature Request]: Improve force RSS behavior when subscription limit is reached #8104
• closes [Feature Request]: Show a message instead of hiding the community tab on the subscriptions page when it is unavailable because of RSS #5716

Description

Show the posts tab on the subscriptions with an explanation when "Fetch Feeds from RSS" or is force enabled because the current profile has too many subscriptions instead of hiding it. It also shows the "Fetch Feeds from RSS" setting as enabled and disables interaction with it when RSS is being forced.

Screenshots

2. Switch to a profile with 125 or more subscriptions and check that the too many subscriptions message shows up on the posts page.
3. Check that the "Fetch Feeds from RSS" setting is force enabled in profiles with 125 or more subscriptions.

Not sure if that dim out effect on specific profiles would confuse users
I don't think we have any profile specific setting so far
If we want to tell user that FT is forcing RSS for current profile (even when force RSS disabled) I think it probably should be done in another way

Taken from issue

Visually grey out the toggle after the user first receives the RSS is forced message. This way, the message will only be displayed once, rather than every time.

Show toast once per tab per session

Also like discussed update the message at

@PikachuEXE what about this: If users doesnt explicitly toggles RSS in the settings then it will be dimmed out and forced if limit is reached in profile A but when user switches to profile B that sits below the limit then the setting will be turned off
