Error with MAXApp on iOS 11.2.5

[victorgrant]

Hello,

I've been using MAXApp on my iPhone 7 for a while now.
It was working just fine when my iphone was running iOS 10
however today that I updated to iOS 11.2.5
whenever I am trying to open the app it is only loading a white blank screen
on it's startup and simply closing itself automatically after few seconds.
Can anyone please help me fix it?

Any help will be apprecited.

I didn't find the right solution from the Internet.
