That is a good idea, but we didn't try that. What I did try is clearing all the cookies/cache and also the site settings in Chrome. After I did that it worked. Then later today, I tried again and it didn't work. But I figured out what I did differently. I closed the Covid-19 travel alert message box first today. Then it didn't work again. I ended up clearing cache and site settings and again logged in and this time I didn't close the Covid-19 message, and just started going into checking for availability and it worked. If I closed the Covid-19 box it would stop working again until I cleared cache and site settings.
I am thinking that Covid-19 box has some bug in it, (no pun intended) when you close it it does something to the cookies or cache. It sounds crazy, but that is what I found when I was playing with tonight. YMMV
