Can the Classic Editor Plugin cause Bing indexing problems?

Hi everyone,

I have been so happy that one of sites is doing well despite a year away! I did just a little with it and added one new post and I have featured snippets on Bing already! This is wild since I don't have many posts on that site. It was just a baby when I stopped and it didn't have nearly the content of my first two sites. I had lots of snippets from those sites but never had one from this site before.

The new post won't get indexed on Bing however. I keep looking up what the problem might be and can't find much. I have gone down the rabbit hole of trying to turn plugins off to see if that helps.

Does anyone know if the Classic Editor plugin which allows you to use the Wordpress Classic Editor causes indexing problems?

Everything else appears to be set up identically with my posts that are ranked 2 and 3 on Bing right now so I don't think it is anything like links, images, ads etc.

Here is what I am getting on the Bing Wordpress Editor in case someone knows what this means.

This next message seems to indicate I am missing Alt text for an image but I checked all three images in this post and all three have Alt text. It says that is the only error and it is low severity so I don't know why that would prevent indexing.

Google has indexed it but says it has problems with breadcrumbs. That is where I ended up thinking perhaps the Classic Editor could be the problem. I have never understood breadcrumbs.

I tried turning off All In One SEO and using Google XML Sitemaps plugin instead.

Does anyone have any ideas?

Thank you so much!
