We have released several children's apps to the app store which are compatible with 7th, 8th and 9th generation Fire Tablets. The apps work fine, but on 9th generation fire tablets (device id: KFMUWI), several parents have complained that they are unable to share the apps with child profiles. We are able to reproduce the issue - when sharing apps with child profiles, they only show up on 7th and 8th generation tablets, but not on 9th generation tablets. The strange thing is that exactly 1 of about 18 apps does show up in the child profile even on 9th generation tablets but none of the others do. We are not able to find anything specific about the app store meta data for that app that would cause this behavior. Please let us know what troubleshooting steps we can follow to resolve this.
