I bought a pack of Bubbies Mochi Ice Cream and I tried to submit a receipt before it expired but there was a glitch in your app. The app kept asking me to add offers to submit a receipt although the offers were already added. I tried to see the list of the offers, but they were empty. Somehow the glitch went away just now and basically I could not submit the receipt on time.
My Ibotta app shows Bubbies Mochi Ice Cream Pack and that it doesn't expire until 09/03/21.
I would clear your cache and try again. There have been issues with the app today.
First of all. The posts are not typically all read by ibotta personnel. This is a forum more than ibotta technical support. That being said we have ibotta liaisons that assist when summoned.
Anyway, I had the same issue you did yesterday and so did many others. if your offers expired before you could redeem, then open a ticket. Include UPC codes and pictures of the items. If you explain the issue. I am optimistic you will get paid.
