It’s been just over 11 hours since I installed V5 Beta on a Mac1.
I did notice that these tools were not loading as expected whether run in Full Page mode or not.
BUT they did load after, I think, nearly 60 seconds had passed.
I reopened just now and the same thing happens – tools not available no matter how you click on them – then loading and usable within a minute or less.
After V5 Beta has been open for a minute – tool dropdowns show up.
