Weird, doesn't show the band and the Reddit forum it says to post on for help has been made private. Only the speedtest work and there is no comparison table or map.
Developer reply
Hi Jonny, Thanks for your review and for alerting us. The app should show the band but occasionally doesn't if the signal is poor. Let us know at signaltracker@policytracker.com if this continues. You should be able to post on the Reddit forum but need to register first. However, also happy to answer queries by email.
Thanks! the ST team
