Cannot highlight or add notes in New Experience

As of today, I cannot highlight scriptural text nor can I add notes via the New Experience on my computer. Each time I try to do so, the choice box for "Mark, Note, Tag, Add To, Copy" pops up but then immediately disappears when I click on one of those options.

It worked just fine a couple days ago, but now it is not, and it is very frustrating. Will it be fixed soon? I am using a MacBook running OS 10.13.6. Thank you!!

I find the New Experience to be intermittent. Sometimes it won't even render content. Sometimes notes don't work. They seem to be working on things. I think we're supposed to have patience.
