Ionic Auth: Should I link to ionic dashboard?

is it mandatory?
I’m now using google plug login.
but it work good and debugging mode
command like ionic Cordova run android --device.

but on signed apk, it has 10 error.

why is it? can’t understand it has error on signed apk version.

I checked below links and it says about dashboard ionic…

Generally, no.

If you want to use Ionic Auth, then yes as it has to be configured there: Appflow Dashboard

But you are aware of this note at the top of the document?

Ionic Cloud has been deprecated. To continue using Ionic services, migrate to Ionic Pro before Jan. 31, 2018.
