[Solved] Long Lag Logging in

I hope this isn't normal.


I just purchased the premium but now I see that lag is a major problem (the last two days).  I wish I would have been more thorough before purchasing.


Is this typical?


It has come to our attention in the past couple of weeks that users were seeing long load times logging in – at first, that it was related to infrastructure, but couldn't find anything to support that hypothesis. Classcraft saves a tiny bit of information on your computer to allow you to login automatically on return visits, so you don't have to type your password. After a lot of digging, we realized that the perceived lag is related to this data getting corrupted in users' browsers. This prevents the automatic login from happening and thus there is "lag".

This is really hard to reproduce because the root cause of the corruption is not yet apparent. We've released a series of fixes last night at 1AM EST and will continue to release fixes in the coming days to help prevent this issue. In the meantime, please let us know at support@classcraft.com if you run into any issues – the more information we have the faster we can fix this.

I thank you for your patience, and sincerely apologize for any headaches this issue may have caused.

Hi Nicholas,

It is not typical--we're currently investigating the issue.

Any additional information could help us. Is it only at school? At what time? On which device? Is it only on log-in? Etc.


Hi --

I tried logging in on the free version today and it just kept circling.  I was able to use the app earlier today.  I am using an iPad mini 2 and this problem happened around 2:45 CST.  Thanks!
