How do I hide offers?
Hiding offers works against the system built into the app and the extension, as both do a great job at surfacing surprise deals which you didn't think you'd want or use, but when you're on a checkout screen and see you have a $50 off $80+ purchase offer on a sock drawer card, you'll be really happy you didn't delete that offer.
The trick to optimizing offers when you have many is to favorite the ones you want to track specifically, as you can filter most views in the app and the extension by favorite offers. Then let it surface all of those other offers in the pointers tab and shopping pointers of the extension, as well as in search.
If you really want to hide offers, you can delete them in the CardPointers app, and can use the Bulk-Edit feature from the Offers tab to do that with 100+ offers at a time. You can also snooze them which will hide them in the app for a few days.
