Firmware Version shows as "null" on android after upgrade to 000.015.00003

Reply from support, worked for me:

  1. Log into the IDE via https://graph-eu01-euwest1.api.smartthings.com/
  2. Click the Hubs tab on the top bar
  3. Scroll down and click into Hub utilities
  4. Under section ‘Hub Commands’ press the ‘Hub Disconnect’ button

Now check in the app after a minute or so, and it should read the correct firmware version.
