When I select the nav bar dashboard link on a local lan connection I get a blank screen with nav bar at the bottom and Green bar with "Dashboard" at the top.. It works as expected with a 5G cloud connection. Hubitat beta version 2.3.9.157. Not sure if this is a Hubitat version or Android app version issue. This did work correctly when I checked a few days ago. Local dashboards work fine from the connect to hub menus.
UPDATE: uninstall and reinstall the mobile app resolved this.
