It's not an amethyst setting, it's your phone setting. Do you have another lightning app on your phone?

Discussion
I have 4 lightning apps and one ecash app. I accidentally selected it to always use the ecash app in Amethyst when sending a zap, and the only way to change that was to uninstall the cash app.
Thanks for heads up, I'll investigate into my phone's settings.
