Stuck on "Adding your account. This may take a minute..."

Hi everyone :) Apologies, I've been a bit under the weather this week and unable to respond to anything directed at me. An update, and to hopefully respond to everything: I did indeed have a security key associated with my account. When I removed it, everything worked without issue. I've updated, however have yet to add my security key back, though I will be doing that soon. I must say, the responses and help I received after making my post were all so wonderful and helpful. Thanks so much to everyone for being awesome! :)
