Android Question Play Protect doesn't recognize this app's developer

[hatzisn]

Hi everyone,

Today when I tried to install an updated version of my app in my device with B4A bridge I got the following message:

"Play Protect doesn't recognize this app's developer. Apps from unknown developers can sometimes be unsafe."

Yesterday this wasn't happening. Did it happened to anyone else also? (Maybe a Google Play update?)
I googled it and there is no information on the Internet with this message. My device is Android 7.

Thanks in advance.
