We have great systems but sometimes we humans miss something!
If you don't see your recent donation on your volunteer profile, it could have been missed in the final number count submitted by your hub leader. To prevent this from happening it is a good idea to pre-check your donations prior to a Sunday donation. But, even then, this can happen and it is easily remedied.
Send a quick email to your hub leader apprising them of the missing numbers and they can submit an edit to the count. Once that edit has been entered by the hub leader it takes 24 hours for update to take place.
