+1 to Apple
This is NOT fixed.
This problem is more common that you think. Stop diminishing this issue or blaming user error.
I am a huge iOS and Apple supporter, and an engineer and software developer, and have been for decades.
Three times on three different devices over the last 16 months - EVERY song-based ringtone I took hours to assign to people, both from iTunes Store, or from my custom ringtones of all kinds (garage band, or anywhere else) have ALL been dropped from my contacts on multiple occasions.
This is really getting old. I know it happened again when I hear a default text tone for a text from my wife. "Uh oh... Not again"
Most recent was around a month ago. I didn't bother fixing it this time, I'm so tired of this.
I don't believe the conspiracy theories that they're deleting our tones so we go buy others. I _can_ believe that tone length requirements change and file type requirements change to keep virus-infected tones off our phone (remember: you're paying for security here, not unsafe flexibility like an android), but that doesn't explain why their own tones dissapear.
This is happening to me with both tones I created AND tone from iTunes. And it is very frustrating since it takes time every time to assign custom tones to key contacts.
In fact, when I just tried to add any custom tone to my wife, NONE of my iTunes or other custom tones are even listed as an option, just the built-in and classic tones.
This is definitely not fixed.
I'm not even going to attempt using custom text tones until Apple reports on this thread that this is fixed.
In fact - let's communicate this in other ways to show our frustration.
If your tones keep getting messed up or you are frustrated about what is happening to custom tones, change your default text tones to "Bamboo" until it's fixed. Everyone will hear the old tone, including Apple.
"Bamboo tone protest"
Apple please fix these issues with tones. I don't want to waste time assigning tones to people again until you have specifically repaired the problem.
