App not working to change tones

Hi I am trying to change my in app notifications and every time I select a different sound, I’m told ‘your sound could not be loaded - try again’ and that just keeps repeating. I deleted the app and reinstalled, and some of the sounds now work but not all. My wife also has the same issue with this. Please advise Thank you. (PS if an admin reads this, the app still advises to email for help, to which you just get an auto response saying help is t offered on email. Quite frustrating)
