Hiya,
Just wanting to provide a bit more insight into the current Login problems with Casper.
Google recently pushed an update to Google Play Services, and have now disabled the older version.
Due to the older version being disabled, the systems and workarounds that Casper used for logging into Snapchat, no longer work.
I've been trying for the last day or so, to get it all working with the updated Google Play Services code, however it's not possible as it appears Google have patched the workaround.
I'm working on a completely different way for logging in, however this may take some time for me to do.
During this time, you won't be able to login to Casper, so... If you are currently logged in, I suggest not logging out until the next Casper update.
If you have already logged out, the only way you will be able to login to Casper, is if your device is "rooted".
With root access, we can completely bypass the login process, by copying the authentication tokens from the Snapchat app after you have logged into it.
Just wanting to inform you all, so you know what's going on.
Thanks.
