Over a month “Waiting for Review”

I have app update that’s been waiting for review since 4th February.

I’ve raised a case, posted to the case a few times, been told twice by support that I ‘haven’t been forgotten’ and yet nothing changes and no useful communication. It’s an update to an existing published app.

I have other apps waiting for review and TestFlight approval for almost as long.

Now approaching 10% of my year’s developer subscription has already been spent just waiting.

What‘s the answer here? I am reticent to reject and resubmit As there’s no evidence that that would make any difference. None of the app updates I’ve submitted for other apps after this one have been reviewed either.
