I can see a WiFi signal in your screenshot. Just to confirm, did you have online connectivity when the basemaps didn't work?
Also, the location icon tells me that you've got location services enabled, but we don't see a crosshair nor is the "add marker" icon enabled. That tells me your device had mo location fix at the time of the screenshot. Did you get a location fix eventually?
I have been bitten in the past where WiFi was enabled, and my device tried to get a location fix via WiFi rather than GPS. However, that WiFi didn't broadcast a location and Collect got stuck waiting for the fix.
