Well, it's finally over. This morning was equally bizarre. FB let me get back in on my phone (explaining that it was because I was logged on Messenger on the same device). But on my laptop, my old PW didn't work because one of my attempts to change the PW yesterday had apparently been successful though it would accept what I had tried to change it to. For a while, every attempt to get to a "change password" screen only led me to a login screen. I eventually got out of the loop and changed the password (after being accused of "engaging in behavior that may be considered annoying or abusive by other users." I was apparently "going too fast when taking an action" and was told? that I "must significantly slow down."? I have no idea what caused the original problem but it's astounding to me how user unfriendly their site can be sometimes.
