WHFB is not working with Server 2019 Domaincontrollers
We had Windows Hello for Business working fine.
We created a new ad forest with only servers 2019, now WHFB is not working anymore.
"This option is temporarily unavailable. For now, please use a different method to sign in." and KRB Error: KDCERRCLIENTNAMEMISMATCH

Not sure the date on this, but yeah and issue. Update your Domain Controllers to at least March 2019 patch set. It appears this was fixed in kb4487044 on Feb 12, 2019. Turned out for me that for some reason the patch guys didn't have the 2019 patches loaded in SCCM. Bwaaahhhaaaa! What a waste of time.
