When I remove a publisher, the modal list updates but the autocontribute box never updates even across restarts:

I've removed sites to leave only 2 but autocontribute says I still have 8.

For next time pls also add 0.55.x here as an indication that it's the first channel it appears on. I review a list of PRs periodically to make sure we didn't forget to uplift some things. I added it this time 👍

this should be done on DB level

[ryanml]

@NejcZdovc I need to be able to show the number of excluded sites for contribute modals restore option, if we fetch only the included publishers, I won't be able to calculate the difference. What do you suggest? Fetching only the count?

[ryanml]

@NejcZdovc - you want to see something like:

export type Excluded = 'DEFAULT' | 'EXCLUDED' | 'INCLUDED' ?

[NejcZdovc]

@ryanml something like this

export enum Excluded {
    DEFAULT = 0,
    INCLUDED = 1,
    EXCLUDED = 2
}
