New App/Firmware broke Hunter fan remote

I am on 2.9.0 of the iOS app with my Bond bridge running firmware v2.6.32. When I upgraded, my existing fans migrated over but were not completely working. Fan on/off and light on/off worked. But, speed up and speed down did not. I decided to try deleting the fan and re-programming. Now, none of the buttons will work. The app throws an error “There was a problem communicating with the device. Please try again later” on any attempt to test the button as part of the programming process:

My Minka Aire fan works great. This Hunter fan now very much does not. Here is the remote I was attempting to program:

My bridge ID starts with BD.

TIA
