Google Product Ads "awaiting review" too long: Need advice

We have 372 product ads "awaiting review" for about four days. Previously we had the 95% of ads running with no problems A. Research online indicates that the "awaiting review" period is very unpredictable and can go on for weeks. B. The review appeared to be triggered by 8 new products added, 5 of which had titles too long. We fixed this and re-uploaded the feed. We are looking for solution(s) in the form of advice for recommended path forward to solve this problem: 1. Advise us how to shorten the review period for product ads We are on the Prostores e-commerce platform. We do not use auto-feeds: We manually upload our product feeds to google because there are so many little details to clean up that we find it easier to maintain a .csv file and edit it as needed, and upload as needed.
