We were collecting all redaction requests, even though we weren't sending out the webhooks. We are now processing this queue and sending those webhooks through. Duplicates can occur on stores that uninstall and reinstall apps frequently for whatever reason. If it doesn't look like these are valid, please let us know.
We are also receiving multiple redaction requests for shop data, even though the user has only removed the store once. This appears to come in 2 days apart ... so far we have seen two or three webhooks for the same uninstall event. Total of ~20 redundant redaction requests. Please advise. Thanks.
