[Android] things disapear after showing a interstitial ad

After closing an interstitial ad some of the buttons and elements in the app disapear.

Loading the ad and events work correctly:
this.ad.onAdEvent((event, error, data) => { switch (event) { case AdEventType.LOADED: console.log('ad loaded'); this.ad.show(); break; case AdEventType.CLOSED: this.routerExtensions.navigate(['postcard-viewer', Constants.Modules.PostCardEditor.result]); break; case AdEventType.OPENED: break; case AdEventType.IMPRESSION: break; case AdEventType.FAILED_TO_SHOW_FULL_SCREEN_CONTENT: console.error('InterstitialAd failed to load:', error); this.routerExtensions.navigate(['postcard-viewer', Constants.Modules.PostCardEditor.result]); break; } }); this.ad.load();

Showing the ad also works correctly.

Once the ad is closed, some buttons and elements are not shown anymore for example:

<Button *ngIf="stateService.freeCard && !loadingQuota && quotaAvailable" [isEnabled]="!showspinner" class="pcc-dark-button send-button" [text]="'viewer.backside.free-send' | translate" actionKey="SEND" (tap)="onSendClick()"> </Button>

Beginne mit dem Interstitial-Ad-Event-Handler und dem im Issue gezeigten CLOSED-Navigationspfad und reproduziere das Problem, indem du die Anzeige auf Android schließt. Vergleiche den View-Zustand vor und nach der Navigation. Als abgeschlossen gilt es, wenn die Buttons und anderen Elemente nach dem Schließen der Anzeige weiterhin sichtbar sind.
