Does anyone know how to fix mPoints or mPlus rewards from Sessions.com?

I have had my S7 for about 3-4 weeks now. I have been logging into various app's that give me reward points called mPlus rewards, with nary an hiccup. Now, I am able to sign into the applications, but UNABLE to get to the achievement page to redeem my achievements as points. My wife has the same issue on her S6. My account is valid with them, as I am able to sign into a site via computer and obtain points. Interesting also, that when I connect my older S4 (running 5.0.1) to an internet, I am able to sign into applications AND get those points into my account. So it seems that the problem may be something in the Marshmallow 6.0.1 build that my S7 is running.

I have cleared ALL application caches, and even the system cache, with several shutdowns and reboots, to no avail at signing into the mPoints gift box in any of the applications. Thinking of doing a HARD factory reset and starting from scratch.

Anyone have a "fix" for this issue? Would be greatly appreciated.

Same issue with my Galaxy Note 4. Started about two weeks ago, now cannot collect any achievements. It was already bad when they reduced the amount for achievements now that I can't even collect them I think I'll just get rid of them. They've been declining for months now and this is just the nail in the coffin for me.
