@benhayward.ben can you explain your comment in the card?

Pro tests are not supposed to run on sandboxes. I can, however, enable them if we can confirm sandbox & proudction are now running on prod / sandboxes

We definitely need to get our e2e tests running on review sites for pro. What's the issue?

Sorry, may have typed too fast - They were initially skipped over because Pro sites were not working on the sandboxes, which they now are (I believe this was around the time the router changes were going in), so they need re-enabling and likely updating so they greenlight. Made a card for this here but I've left it in follow-up as it needs further breaking up. #2316

This, however, is actually under the marketing banner so it is unrelated to that anyway, I hadn't realized at the time.
