New Content Not Showing Up

Hi!

For a few years now I’ve experienced issues with my computer’s browser (pick one…I use Chrome but have tested this in Safari and Firefox) showing me a perfect reality. How things should be looking without issues. Come to find out in incognito, the changes aren’t there or things aren’t right. This has been various things but today…today it’s my brand new post. I see it on my site’s blog page. It says it’s published, the link is live and works and it works from social media. In my Chrome, it’s right there as usual and as it should be. However, if I got incognito or go to my phone or my friends check it, it does NOT appear on my blog page. I send them the link and it works but it doesn’t show up. Therefore, my mail service doesn’t pick it up and it didn’t get sent out to my mailing list. What is going on? I’ve cleared browser cache, gone through my W3TC and tried purging and even playing with different settings. NOTHING makes the post show up. Please help…it’s one thing when it’s an Instagram feed or something that doesn’t truly matter. But my brand new content matters and needs to get to my readers and this is ridiculous. Thank you in advance!
