No worries, it happens to the best of us! If you missed a section or part of your receipt when you were taking or uploading photos of it, simply wait for that incomplete upload to be finished processing before you can claim those offers in the app once again — then re-upload your receipt, making sure to include your entire receipt from top to bottom.
(If you end up missing out on an offer that ran out while you were waiting for your original incomplete upload to be processed, please create a support request and a member of our team will gladly help you fix it.)
