There’s a way to stop that push notifications by simply not allowing it, and on every apps they have notifications not just in gambling. Having this kind of feature might trigger you to gamble more so better to turn it off and just allow notifications for the most important apps like social media platform and banks transactions. If you are into gambling, this might also help you to get updates from your bet online but then again be more responsible.
It's wise not to put full attention on those push notifications so that you won't gamble anytime you sees them on your phone screen or pc monitor. It's would be okay and more matured to turn the notifications off so that anytime you have spare money you can only visit the gamble site or app and test your luck.
