Anybody else's top link bar in Modern experience disappear?

We have a classic site (STS#0) with publishing activated and found some of the links from goblal navigation disappears and it happens only modern pages (Site Page). It seems the links which are pointing to a site page are disappearing.

There is a chance that the below link doesn't appear in the global navigation. 

https://tenant.sharepoint.com/sites/site1/sitepages/sp1.aspx

Change the link to https://tenant.sharepoint.com/sites/site1 and it will appear. 

It seems, the publishing feature caching mechanism is not capable of hanling the navigation nodes pointing to modern site pages. 

I hope this helps someone.

I don't know if this will solve your issue, but for me going to Title, Description & Logo, and changing the Web Site Address worked for me.

I don't know what it was about my URL (just a single word) that sharepoint didn't like, but this fixed it for me. Changing it back to the original breaks the global nav again.

Sam Larson I'm having this issue now as well. For me this is totally bizarre. I have many subsites that have been around for 1-5 years, none of which are having this problem. I created another subsite today, it has the exact same settings as all my other subsites, yet it is missing the top navigation on all modern pages. No matter which setting I choose for top nav, it stubbornly refuses to appear.

Sam Larson Just a bump and update for @TLavallee19680313. One of our clients started experiencing a similar nav issue on the 9th April. No resolutions yet.
