If you send an iMessage to help@impending.com we could try briefly putting the icon in the day’s shop when you’re around to check it. That should let you grab it again for free.
I don’t have a good theory right now though why it’s not restoring, but will have to see if we could reproduce it here. You don’t use multiple iCloud accounts or something do you?
Also just sanity checking, you mentioned it wasn’t in your Themes section. Did you check the separate Icons section too? (Home>Personalize>Icons)
Yes : no multiple iCloud accounts and yes, I’m checking in the “icon” section (sorry for writing theme).
Looking inside my settings, I just noticed the beta of clear was still there. I deleted it, tried a restore purchase again, restarting my iPhone, sadly with no success.
Ok for your solution. I send a mail at this address.
