In the new app (I'm on v2.0.3 (299) but this has been an issue for several releases), the easiest way to swsitch between my multiple locations/hubs is from home clicking on the guy on the top left to open the "my Account" tab, then clicking on "Registered Hubs."
It appears likes there's a transparent layer with a white border sitting on top of the of bottom row of each hub section. This "layer" makes the buttons unclickable. I know there's other ways to get to the various hubs, but this is the easiest and quickest, and I am surprised no one has addressed it. I have brought it up with support multiple times with... unsatisfactory responses.
