Gift Aid claims in webview

The new Gift Aid claim process in Webview was rolled out well over a month ago, and so far it's been nothing more than a headache for us and we have been unable to submit a claim as yet. We've been backwards and forwards with Blackbaud support as claims kept getting stuck on the 'Processing' phase on Webview, even though a query run in Database View would show that a claim ref had been allocated to gifts, so they were being picked up. We then have to run a query and global change to remove this gift ref, which takes hours to process, before we can try again.

After multiple messages, we were told that claims over 10,000 gifts would not work, and that the 'Update Gift Aid status' process that needs to be run before making a new claim could not handle any more than 2,000 gifts at a time. We have between 30-35,000 gifts that we claim on each month.

We were advised to separate into smaller claims as a workaround, but this is extremely time consuming for us if we need to update gifts in blocks of 2,000 before even starting 4 separate claims for a single month of Gift Aid. We've been told there is no ETA to get this fixed, just that they are 'working on it', but it's already been over a month since webview was launched and it's still not usable. It's crazy that database view has also been turned off so there is no alternative to get our claims done.

Is anyone else having the same issue?
