I was able to reproduce the first bug — LinkedIn cannot generate a 
preview for an IDN with U-Labels, like https://ønskeskyen.dk , but can 
generate a preview for the same URL as A-labels, like 
https://xn--nskeskyen-k8a.dk/ .

I was not able to reproduce the second bug — LinkedIn can generate 
shortlinks for URLs with path parts which are posted in LinkedIn 
announcements, but trying to follow the shortlink produces an error. 
When I clicked on the shortlink, my browser delivered me to the original 
URL with no apparent problem.

I do think this story is a reality check for how difficult it is for 
individual customers to get the attention of a business, especially a 
big business, about technical and international matters like Universal 
Acceptance. I think we must encourage customers to ask their vendors to 
fix UA problems. We must, however, be realistic that this will be like 
rain on a granite boulder. There will be no apparent effect for the 
first many raindrops. If we wield the chisel of ICANN's name 
effectively, we can help the raindrops succeed much faster.
