Email Composer : isAvailable -> undefined

I use native plugin

import { EmailComposer } from '@ionic-native/email-composer';
constructor(private emailComposer: EmailComposer) { }
this.emailComposer.isAvailable().then((available: boolean) =>{
 if(available) {
   //Now we know we can send

is undefined now…
Before i had it working properly, it were true and i not tested it more. Last changes, upgraded to 3.9.2 (was looking for promissed 4.0), probably it caused of problem.

Now i have ignore availability check to reach send mail dialog.

Ionic CLI version has nothing to do with it.

Did the Ionic Native plugin version or Cordova plugin version change maybe?

cordova-plugin-email-composer 0.8.7 “EmailComposer”

(Ionic Native email composer plugin version number is in package.json)

@ionic-native/email-composer”: “^4.2.1”,

It surely were upgraded.

So was it upgraded or is it the same version as before when everything worked?

I downgraded to

@ionic-native/email-composer”: “^4.1.0”

problem still exists.

Yeah but with what version of Ionic Native plugin and Cordova plugin did it work before?
