Out of date receipt not containing purchase just made

Over the past month I've been seeing a recent spate of customers suddenly having IAP problems where they are not getting their purchase because Apple is not providing an up to date receipt.

To be clear, this is for consumable IAPs.

This is super frustrating because nothing has changed from our side. Apple developer support have refused to investigate and say they aren't technical support.

Yes I've told the customer to uninstall/restart/reinstall the app from the MAS which should force an up to date receipt but it still doesn't work.

One customer went through the Apple support process and was simply given a refund, which is totally unhelpful because we've already had to manually add the purchased product and now we've lost the revenue and it doesn't get the problem fixed.

Anyone else having similar problems?

It seems overkill but I think I'm just going to call receipt refresh on every single successful transaction, since this does always work to bring the just purchased transaction into the receipt.
