[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>

Commencez par le gestionnaire d’événements de la publicité interstitielle et le chemin de navigation CLOSED indiqué dans l’issue, puis reproduisez le problème en fermant la publicité sur Android. Comparez l’état de la vue avant et après la navigation ; c’est terminé si les boutons et les autres éléments restent visibles après la fermeture de la publicité.
