I've noticed that none of my notifications are coming through while on Wifi after the recent update a few days ago. Notifications include Instagram, Snapchat, Twitter, Reddit email, Gmail. Once I disable wifi, it begins to work again.
I've rebooted my phone and it has not resolved the issue. Another user with the same phone in my household does not have the same issue while on the same wifi. Any suggestions on how to troubleshoot/resolve this issue?
