When you sign in to M2 it will prompt you to answer
the query 'Allow' location, if you have not
clicked yet to 'Allow' M2 to access
your location.

If, like me, you clicked on 'No' starting months
ago, it has now changed and answering 'No' will
now get you blocked from the site.

After spending a long time trying to figure out
how to get back on M2, here is a SIMPLE way.

Click on the icon just left of your address bars
current locale (Mingle2) the dropdown menu
should have 'Location' and 'Allow'.

Once that is clicked you should be able to access
M2...as you can see, I have ;-)
