Probleme mit der Premium-Version nach Gerätewechsel

Ich habe die Premium-Version der App gekauft und war anfangs zufrieden, da alles gut funktionierte. Jedoch nachdem ich die App auf ein neues Handy übertragen habe, treten Probleme auf. Obwohl in der App angezeigt wird, dass ich über eine Premium-Mitgliedschaft verfüge, wird weiterhin Werbung eingeblendet. Dies entspricht nicht dem, was ich erwartet habe, da eine Premium-Version normalerweise werbefrei sein sollte. Ich finde es wichtig, dass das Problem behoben wird, da es das Nutzungserlebnis erheblich beeinträchtigt.
