PWA :tel link is not working ONLY when added to homescreen on Android

[navogel]

This is super weird, and my team cant figure it out.

We have a perfectly functioning PWA in --prod but recently a tester pointed out that the tel and geo links were not working. We realized that the issue is only when accessing the app from a saved homescreen icon in Android only. When accessing through the normal browser everything functions as normal.

We have tried the whitelist issues:

Here is the code in the app:

html:

<button ion-button id=“card_butts” icon-only [disabled]=“isCallDisabled” (click)=“makeCall()”>

.ts

makeCall(){
window.open(“tel:” + this.phone);
}

My lead dev thinks it is an issue with the manifest.json, but other than that we have no clue.

<access origin="*" />
    <access launch-external="yes" origin="tel:*" />
    <allow-navigation href="tel:*" />
    <allow-navigation href="http://ionic.local/*" />
    <allow-intent href="http://*/*" />
    <allow-intent href="https://*/*" />
    <allow-intent href="tel:*" />
    <allow-intent href="sms:*" />
    <allow-intent href="mailto:*" />
    <allow-intent href="geo:*" />
