Android Question Signature Poblem

[EvgenyB4A]

When I build APK with B4A v6.30 and try to update the apps that were built by previous versions of B4A I can't and get the error: "An existing package by the same name with a conflicting signature is already installed."
The application are being installed not by Play Market.
What can I do?
Uninstall the previous app is not the way because I also update the apps online.

Are you using your private signing key?

No. I didn't use any key and didn't open the menu in both in previous and existing versions of IDE.

Uninstall the existing app from the device and run it again.

I know, but I have the apps that are being updated online. What is the default signature key on the previous versions of B4A?
