Thank you.
I went to apps/menu/ and reset defaults. There was no prompt for "which app to use to pick the sound." Cannot figure out how to get there, and when I search for "Media store" nothing comes up.
Under the "Sounds and vibration" title in Settings, I went to Notification Sounds, but only things listed are Default Notification Sound (for the Verizon thing), Messages notifications , and Email Notifications -- but it's ON, and the only other options are Notification sound (which goes to emulated storage) when I click on it. Also, I don't want a sound when I receive an AquaMail, only when I send it.
More thoughts?
Thanks.
