I've also been having all of the same issues for months now.
Receipts take ages in the review, only to get declined (often with NO reason given). The receipt scan records themself often get deleted from within the app so I can't look up old rejected receipts to see if I notice a trend.
When I rescan all of my valid receipts that were declined, they automatically get declined as duplicates.
It takes 8-14 receipts to get 6 successful scans (to get me that whopping $0.10-0.11 bonus), which I don't always have in the 14 day period.
I have noticed that they often reject the smaller mom and pop type stores, non-chain convenience stores/bodegas, etc. A Quiznos receipt seems to have been rejected because the date was oddly formatted as "Apr dd, yy".
