GR86 Carsifi issues

[Grblue86]

Hi,
Just wondering if people have upgraded their phones and have had issues with the carsifi app after.
I did and cannot open the application anymore and I cannot find it in google play to download again.
Found an .apk online sonewhere and tried that too and did not work

When I got a new phone and transfered all my apps Carsifi didn't transfer over. I have found it google play store but it turns out I didn't need it to connect to my S25.
