I Have been tidying up my series links and managed to delete all the old links except one and this has updating next to it for 24 hours. I've tried turning the box off and on but has made no difference.
I'm sorry that the removal of series link wasn't processed properly. Whenever you're looking to clear out anything, be sure to check out our Clear and Reset feature. You can choose one of the 4 options to suit your needs
Using the reset does seem overkill for trying to delete 1 series link. You could use the delete series link and thumbs option I guess if you only had a few series links. If more just best left as probably not causing any harm.
