This WiiYii application is not compatible with my Xiaomi Redmi Note 9 Pro and Google Play Story does not allow it to be installed.
Do you have any alternative to install?
The map does not open on another cell phone and does not find the bluetooth.
I downloaded it over the internet WITHOUT Google Play Store and the map does not open.
I thought this was more easy and functional and not so complicated and the seller said it worked with google maps and it's in the Aliexpress ad.

O mapa não abre em outro celular e não acha o bluetooth.
Baixei pela internet SEM ser pelo Google Play Store e o mapa não abre.
Achei que isso era mias fácil e funcional e não tão complicado e o vendedor avisa falado que funcionava com o google maps e está no anuncio do Aliexpress.

Hello, I just got one but it doesn’t show my speedometer readings.
