If I'm recalling correctly there were only a few significant glitches. Some folks behind the scenes at the Giro complained about lack of precautions -- no masks, etc. -- in common indoor spaces. Some folks ended up testing positive and had to withdraw. That surprised me because Italy was hit hard in the springtime.

There were probably other problems we haven't heard about yet because the teams don't want to alienate their hosts. Eventually we'll hear more, especially after participants are set for 2021. The racers and crews who don't participate will probably feel free to air some grievances about the 2020 races.

But overall things seem to go remarkably well. Although I wonder how much of a revenue hit the sponsors and organizers took. The hospitality industry along the grand tours this year probably suffered from the sparse attendees.
