I'd be interested in this answer, as well. On a previous visit, two years ago, my family had a virtual time for Guardians. Our time was called up earlier and we were in the middle of eating a nice dinner. It never occurred to us to go at a later time, so we missed out. I am planning on doing a LLSP this coming trip. Purchase options available in the morning.
We used ours later earlier this week. It flashed blue and I started to explain to the CM why we were late, but she stopped me and just said oh no worries you're good to go, so it seems nothings really changed with that.
