FIX^^
~~
Today the services were in and out all day and it was inconsistent across accounts. The issue (as far as we know) was not directly related to the volume of people online. Today we would have as many as 1,000 boards online at a time. But we were prepared for that, as Christmas is always 5x the volume of other days.
What seems to have happened is one specific interaction in the Chess.com API (specifically authentication of the user login) was inconsistent today. We are not sure if it was on our end or not. We froze changes a couple of days before Christmas - expecting the upcoming surge and also general lack of ability to do much during Christmas. Regardless, something broke today. We expect to be able to resolve it tomorrow working with Chess.com (who has been great at supporting this project).
Sorry for the inconsistent play issues. Good news is that Christmas is now 364 days away. This means all customer support levels out, and everyone is back in office to support and resolve.
New features (checkers, more 2 player features, lessons, embedded bots, lichess) - are all much closer than it seems. December was swallowed by Christmas demands on the company - we are now past max q and progress will be much easier and swifter now.
If you are waiting on support, please be patient for a couple of days
Chess.com play and WiFi stuff will be really smooth. Remaining feature development resumes. This was just a very demanding launch and now we are rounding the corner.
I promise these issues were not representative of the ChessUp experience. They are short lived launch bugs. We stick with every customer and issue until resolved.
