Vpn safety dot not working

Uninstalled seren and the safety dot went with it. Can not get it back. The RAI just keeps trying but no go. Tried using downloader but same. Using nvidia shield. Just downloaded the dot on my kindle. Works perfect.

Make sure you have deleted the older APKs and then try a fresh install. In downloader go into files on the left and delete any APKs you’ve already used. In the RAI go to the gear icon on the top right and clear files. Then try again.
