I bought it to replace the previous sixth version of the bracelet. The new one is better, the screen has become larger. There were no problems connecting to the Zepp Life that I used before. Deleted the old one from the connected devices, then connect a new device, then when choosing a connection without a QR code. The smartphone also detected a new device of the seventh version in the same way, downloaded new software. Naturally, everything is in 2022, all previous features have been preserved.
