April - as a super temporary fix, can you try changing your timezone on your computer to be Arizona or Hawaii, reopen your browser and try logging in.
If that works, everything will save correctly and send to QuickBooks correctly, it will just display the time in a different timezone. We think the problem is confined to some users in the Pacific timezone, and hope to have the issues fixed up within the next few minutes, so check back shortly to see if we have an updated solution for you. The solution is just going through sanity testing by the dev team right now.
