Just found a weird bug that has only started happenig today

I have Pocket tube (free limited version) installed for ages.
Now when i click on mark as viewed i get a notification from pocket tube that i have exceded my quota.

Was working fine yesterday.

If you need any other info, windows 10, adblocker installed, ghostery installed to get around youtubes ad blocking.
Been working fine for months.
Any other info needed just ask

Mac.

Ok Ignore this, its the other plug in thats broken.
I assumed that the mark as watched was yours.

My Bad.
