“Exactly what was found if not “soft tissues/blood vessels”?
What was found that could be sequenced?”

Possible fossilized soft tissues/blood vessels.

They claimed to have found “collagen” but there was some issue as to sample contamination.

There is plenty more research to go here, but the claim that they found “soft tissue” is incorrect.

I know the objections about contamination, at first it was bacterial “slime” and possibly in Israel it was someone may have some left over ostrich material in the lab hence the dino to ostrich link.

But contamination would raise another problem, that is if the link to dinosaur and bird is due to contamination then there really is no link to be found in the lab at all. OR

Horner, Schweitzer, and, I forget the other fellow's name, are the best of the best with the best and latest equipment yet cannot even run a amino acid sequence without botching it? Or perhaps the objections of contamination have nothing to do with contamination of the test so much as contamination of the science by prejudice.
