Hi, @Theeembp, as you have deleted your Blaze from your app, I would suggest going into your phone's bluetooth settings and selecting forget/delete this device.
That should enable you to set up your Blaze again, following the instructions to set up a replacement device.
Please post again if yu continue to have issues. There is always someone here to help.
Sense, Charge 5, Inspire 2; iOS and Android
Best Answer@Theeembp I'm not sure what phone the app is on, but there was similar post earlier today in the ios.
