My back page button won't work while on android pit

Hi all
Got a problem while on android pit.
Everytime I get a response email from andriod pit i tap on the link to go directly to andriod pit. Everything works fine untill i try to use my backpage key, and it won't work!
It just sends me to the bottom of that particular post. And then i have to close the tab to unlock the screen.
Anyone know what might be causing this?
Somethimg to consider,
I have shut off the storage permission for google play services and i have to turn it on to send a email the regular way, could that be messing me up when i'm on android pit?
