With so many unknown variables its very hard to really know… the reason I ended up on WDD was because of cooldowns very early on in my wayfarer career as i had seen reddit posts and such about the shorter cooldowns and nothing about the 24hr one… I never did solve it just found I really wasnt the only one.
It doesn’t seem to be happening to everyone. If it was, I think we would have more people wondering what was going on, and we don’t currently.
Letting a review time out while you are on the page is extremely unlikely to cause a problem. If you switch to a different page (e.g., check your profile, go to another website) and then switch back, the same review is still there and the (hidden) timer is still counting down. This means if you leave the review page, so as not to leave it open when you walk away, the review will still time out.
