Gospel Library won't load into child profile--record audio the problem?

Currently I know a number of Kindle fire users who can no longer get the Gospel Library to load into a Child's profile after the Nov. 5 update of the app. I've emailed the Gospel App developers at the church but have gotten 0 response. Recently, I posted the issue on an Amazon forum and received this information:

"I noticed in the tech details one of the permissions is to record audio. If that works like Alexa, access to that is blocked in a Child Profile on a Kindle Fire. That could be what is stopping the app from loading."

How can I get this information to the developers? I seem to running up against a brick wall. Maybe they don't plan to change it, but it would be nice to know. I know a lot of parents will be sad their kids' Kindles can't have the Gospel Library app on it anymore.

I am having the same problem. I purchased 2 of the new 2019 Fire tablets for my kids for Christmas. I wanted the devices so they could use the Gospel library app. However, I cannot add the app to the child profile. This defeats the whole purpose of purchasing the Fire tablets for them. Has anyone found a solution to this? I spent 2 hours on the phone with amazon techs to try to problem solve and nothing resulted. To make things more strange, one of the tablets, allowed (at one point) the app in one of the child profiles, so he is able to use it like normal on that device in that profile. After a few days it would no longer show the option to add or delete the app from the child profile. So, it's like something happened with the app during that time. On the device that I added it to, before whatever update they did on the app, my son can use it like usual. But, I can't add it to my son's profile on the other device. I would love to be able to find a solution to this. I can't be the only person who wants their kids to use this app freely on a Fire tablets. This app is why I bought the tablets.
