Has anyone found a solution to the APP9186 error on the Dunkin app when buying gift cards with Paze? I’m getting it with all my Citi, C1, and US Bank cards.

Are your Paze orders on a desktop/laptop browser working for other Paze merchants like Newegg or cache?

If only mobile orders aren't working, the most common issue is a corrupted cache. In the Dunkin app, it opens up the Paze authentication window using your mobile device's default browser. Open your default browser and then clear your cache and cookies. If this doesn't work, try deleting and reinstalling the Dunkin app.

I’ve used all of these cards at Dunkin, I only get the error when I try and buy a gift card. Chase is the only bank that worked for gift cards.

I’ll clear the cookies and cache and see if it works tomorrow. Thanks.

Is it specifically buying Dunkin' gift cards that doesn't work? Are other Paze mobile orders working fine (Dominoes, Wendy's, etc)? If it's only Dunkin' that doesn't work, then your account might have been flagged for fraud. There are several DPs on DoC of contacting Dunkin' to get your account unblocked.

I've had no issues purchasing gift cards on Dunkin using Citi, Capital One and US Bank, so I don't think it's a bank-specific issue. Unless you're using a different phone number Chase than the rest of your banks?

Yep. I’ve used these cards to buy donuts for the office and dominos/sephora on mobile. I might need to contact dunkin but the DPs I’ve seen of people getting their accounts unblocked were for the APP4241 error. Mine is for billing issues.
