Premium features in adobe express mobile app have stopped working

Hi all

ive been using adobe express for a couple of years now with a premium subscription with no problems. Using the mobile app almost daily creating instagram content. A couple of days ago my premium features stopped working properly and I can't use any premium content or it works intermittently for a few minutes and then I can't access the same post again. It's driving me nuts. I've checked my account on desktop and it's fine. What is the problem?
