Die einzige Lösung, die ich gesehen habe, war eine Antwort auf eine Stapelüberlauf-Frage. Ich habe den Link unten gepostet. Die Antwort, die ich beziehe, ist die fünfte. Es scheint jedoch, dass einige Benutzer einige Probleme mit der Lösung haben. Ich weiß nicht, ob es eine andere Kategorie gibt, die verhindert, dass zwei Controller gleichzeitig gepusht werden. Alle mögliche Spitzen oder Vorschläge werden geschätzt.
