Staff is incredibly backlogged at the moment and likely inundated with 100s of emails. We've found that eventually emails are returned but it can be a week or more and these are for non bug related communications. Bug report e-mails are probably just shuffled into a pile with the rest since staff probably already knows they exist.
One thing to keep in mind is it took several weeks for new creators to even be able to click the button to join ad revenue even after it was working again for everyone else who joined before the migration. So it is likely going to take a while to get the impressions to start updating. Hopefully it will be retroactive.
Getting search back onto the app took about six weeks? Getting the forums turned back on took four weeks? These are just guesses. There are only two software engineers at the company so its just going to take time. Considering that they got it working again where new people could post to the forums on a Saturday at 10 am, the engineers are working at least 6 days a week. There is probably just a mountain of higher priority stuff they have to do first.
