From the research I've done, it apparently has to do with the third party cookie filters in regards to the recently added Google One account logins. The suggestions were to enable (stop filtering) "third party cookies", in our browser and on our computer. Now I don't know about you, but I'm not really comfortable with changing that feature. I was secretly hoping Google would fix things. HOWEVER, I have just learned there is a way around it. Thanks to Helen from Crafting Helen, who suggested to just leave the CAPTCHA area empty and simply click the 'publish your comment' button anyway. So, far I've done exactly that on four separate comments I've left on different blogs and they have all been published.
Just thought I'd share this with you in case you're experiencing the same frustrations. Hopefully, Blogger won't realize the mistake and we'll continue to be able to it this way.
Until next time,
