On Android note 9, reinstalling the app makes the cha Ching come back for only a day. Then it disappeared from custom notification sounds again in android settings. So I used the files app on Android, copied the Shopify cha Ching file to different folder, renamed it to something else, then back into notifications-shopify-orders, then I selected my renamed version of the cha Ching sound. So far it's stayed...
Hi this happened to me as well, lost my chaching recently !! Android S20 none of these suggestions worked at all. I had to do it the hard way.
1. On your phone Download the cha-ching sound here:
2. Follow these directions to add the file to your notifications library on your android.
Basically you go to MyFiles on your android> find the file in your downloads > hold and press it > check move> go back to your notifications > messenger folder and place into there.
3. Then go to your shopify app> settings> notificaitons>open settings >orders>sound >select your file
So satisfying, Worth it. and then once I did all this the option to install shopify sounds finally showed up... figures. But if all else fails this will work
