I'm using the RE550 range extender and it works great, except for 3 apps. 2 are games and the other app is Telegram. If I want to play one of the games, I have to switch to either mobile data or my non-extended Wi-Fi. Same with Telegram. Every other app I have works fine. Telegram won't connect using the extender so I never get notifications unless I manually switch networks. Is there a workaround for this?

Thanks in advance!
