Need tech help

I just got a new IPad
For some reason I cannot post on it.
Even though I have logged in, the “Log In button still appears in upper right corner.
When I hit Reply on a message, I get a message “Authorization timed out, or you have switched browsers. Please try again.”

This is maddening

Works for me and I only use an iPad for the site. When you logged in, did you click the little box to leave yourself logged in?
