So you are playing on Android? My guess is you did not install version 7.7.1 of the Renpy Plugin. Do the install again with that version, then it works.
More info on the FAQ page in the Wiki and FAQ channel in Discord.
I noticed you asked the same thing 15 days ago, and I answered then same way I answered now. What happened? Did you not use Renpy Plugin version 7.7.1? To find where you can download it, see FAQ page in the Wiki.
