I just got the Rose 150B last week. I initially set it to wi-fi using my eero 6pro mesh system, then I downloaded the app from Google Play. Then this error message:
It says Versions of Rose and Connect are not the same-Please use them after the update.
There is no update. I also installed rose connect premium on my android phone and got the same error.
Also, I switched to ethernet and tried to install the app and got the same error messages. I’m thinking factory reset-set as ethernet-tethering and set my android phone and tablet to wifi hotspot to see if maybe that will work.
