Hi, doesn't look like you've received any responses yet. My situation is a little different, but still similar to yours. Here's my (limited) experience as a new Amplifi user.
Amplifi 30 and the Ampli FX 100, both updated with the latest firmware
iPad 3rd generation w/last version of iOS 9.3.5
Android phone with latest version of Android 7.1.1
Amplifi remote app, version 2.6 on both devices
Although I'm still getting my feet wet, things seems to be working as-intended. Given that my iPad is older than yours, I'd expect that your results should be similar.
download the current version of Amplifi in the apple store, when the message appears that ios is earlier than 10, quit the app, and re-enter the app and re-install the Amplifi, which will automatically display the previous version installation option. I did it on my ipad 3 ios 9.3.5 and it is working very well
