Updating block list - search crashing

Hi all
I am simply trying to add a new app to my whitelist; when I go into my app list and search for it I get the dreaded “this Apple screen has crashed”. :sob: it’s getting really frustrating - it shouldn’t be this hard to simply ammend a block list. I know it’s not fully in Opals control but I am finding it hard to justify the cost of the premium subscription. If there is anything I can do, please let me know! (App is fully updated)
