Great features to make the game more fun but for some reason I've noticed I have to refresh my game each time I want the effects to take place. Can this be fixed?

Great features to make the game more fun but for some reason I've noticed I have to refresh my game each time I want the effects to take place. Also there is a weird motion blur and the player models don't appear when playing duels. Can this be fixed?

Really cool extension! All the modes like Pixelate, grayscale or hidden car and so on... bring in a lot of variety. You suddenly see places with completely different eyes. It's stable and easy to use - exactly what GeoGuessr was missing. A clear recommendation! [EN] Richtig coole Erweiterung! Die ganzen Modi wie Pixelate, grayscale oder hidden car und so weiter... bringen super viel Abwechslung rein. Man sieht Orte plötzlich mit ganz anderen Augen. Läuft stabil, ist einfach zu benutzen – genau das, was GeoGuessr gefehlt hat. Ist eine klare Empfehlung! [DE]
