Duelbits balance sync?

has anyone else noticed weird timing on the balance updating across devices? like, if i leave a session open on my phone and then log in on desktop, the numbers don't always match up right away. i double-checked everything, even reloading, but sometimes it just takes ages or i get kinda freaked thinking my balance is off. is this just a normal thing with these crypto sites or should i be more worried? i keep telling myself to wait it out but patience only goes so far. anyone else run into this?
