Hello @Brad Keller (Technical Specialist - Cloud) ,
Thank you for reaching out to the Microsoft Q&A platform. Happy to answer your question.
I understand you are unable to select newest image definition from host creation interface in AVD.
I am quite not sure about the root cause of this issue, however for a quick work around, I have a colleague who experienced this before and to fix, they have started naming the images with version 1.0.0 instead of 0.0.0. There is still a slight delay and waiting for that version number to populate but it does work.
I will check internally if there is anything that is known already for this scenario and update this post.
