I'm having the same problem with my android. I can no longer sync between my phone and desktop.
And despite what some may like, I actually think the new look is kind-of ugly for Android. The app feels way less performant, search is slow, and the UI feels really cluttered now. It just doesn't feel like the smooth clean Android app we had in v5. UI wise, I might be able to hold my breath and deal with it, but not being able to sync between my phone and the cloud really kills the usefulness of Enpass all together
