screen shot on marshmallow not allowed in certain apps! How can I fix this?

[AC Question]

"Couldn't capture screenshot. Can't take screenshot due to limited storage space, or it isn't allowed by the app or your organization" I have plenty of storage so I know that is not the problem, but I get the problem with banking app, Good Mobile, MyQL...? How do I go around this?

Its because your banking app doesnt support screenshots due to security reasons .
