I thought that perhaps I could email the post to Blogger. That did not work either. The email bounced back with the following:
Technical details of permanent failure:You have exceeded the the allowable number of posts without solving a captcha.This happened because I imported quite a few blog posts from another blog I discontinued just yesterday. It has been less than 24 hours since the import. It makes sense. I'm rather certain the captcha speedbump is also why the mobile app refused to publish my posts.
The problem can be circumvented if you post directly on the Blogger site and solve the captcha. This problem will likely resolve in the next few hours and all will be right with the universe once more.
