something is up with "my bets" its showing random bets from all my accounts
It is normal behaviour, if you use the same browser. As your bets are stored in the cookies, it will show the last 30 bets and if you had only 2-3 with one account, then it can show bets from 10-15 accoutns too...
First of all its not possible to log into multiple accounts via the same browser, the only way out is creating an incognito session for a new user login, and for that also, the bets aren't stored in cookies, its the session data that gets stored into the cookie, and for an incognito window a different cookie folder is available that prevents the mixing of the cookies of the main browser with the cookies for the incognito browsing. There is no way that the cookies have merged to show up this result. There is something wrong with the server side and not the client.
You dont have to be logged in to all the accounts, just logint to one, make some bets, log out, and login to another account, then you will still see the bets from previous account...
