Smoldering Durtles app not working

Cannot get the app to accept an API code on my Galaxy S24. Older devices work fine but would prefer to get the app to accept the token on my daily use device. When copy pasting the API code the app will just flash white then blank out the API code field. Anyone else having this issue?

Recently ran into the same issue on my S25–I double checked permissions (my app had been put into deep sleep or smth automatically), cleared cache, and generated a new API token.

Hopefully the same fix will work for you!

Clearing the cache worked for me! I didnt realize “storage” under usage was a button. I kept uninstalling and reinstalling the app without success.
