I'm experiencing similar issues, logging out every 5-10 minutes too. Hopefully, they'll address this soon to provide a smoother experience.
You guys have to accept that as part of Betpanda features unlike other casinos like Stake that keep a user pernenrmently logged in on the same browser, Betpanda has a system that auto logs users out at regular intervals.
What I will advise you guys to do is to try and save your login details on your password manager and auto-refill them anytime, at least that is how it works for me, until the team finds a way to work on that feature since many players are already complaining about it.
Where can I see it written that they have an auto log out? Because when I try to play when I join the multiplier contest, that has never happened to me, and I'm just curious because the experience really isn’t good if there is an auto log out, or maybe it’s just that the user is using a different IP, or a VPN, so it logged out.
