Sorry to hear that!
Can you please grab this app and put your phone either outside or by a window, somewhere with a good clear view of the sky for a while so it can grab the current satellite almanacs, assuming we don’t have a hardware issue?
It should show you every satellite and SBAS your GPS receiver can see and a bunch of other debug info.
Give it at least 10min to work, though up to an hour can happen some (rare) times.
Please post a screenshot of what you get so I can help read the results.
If you have a hardware issue, you’ll need to reach out to support@myteracube.com for a Warranty repair.
