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.

TLavallee19680313 - At this time I'm unaware of any major issues with this occurring again. Please open a support ticket and the team can investigate. 

Sam Larson I just had my top navigation disappear today from my SharePoint site where I use modern pages. I saw this post but from back in 2017. Looking for any advise. 

Sam Larson Thank you for your quick responses. Our managed navigation is working today. 

We've determined that an update which routed users utilizing navigation links was removed in error, resulting in impact. We're working to identify the optimal method to restore functionality.
We have posted this issue under SP196097 for the affected environments.

Hi Lauren, you may be running into a separate issue here. The issue discussed earlier in this thread was actually a regression that was fixed in December. To my knowledge this is not occurring again however if there is another regression it would help to have your tenant details. If you can get a service request opened via https://admin.microsoft.com we can further investigate. Thank you!

Sam Larson This same problem is happening to us today. Ctrl+F5 isn't helping. Is there a way to fix this? We rely on the Managed Nav. 

Same here

This issue has just returned... :(

Thanks for your good work, Sam!

This should now be resolved as well

Thanks for posting this issue, i'll investigate and post once I have an update.

I see this, too, and it's less than helpful. Looks like it still applies to only Publishing sites. Sam Larson, is this an intended rollout or another bug?

Finally this morning the top link bar was back.

Think I'm last on the list for everything :-)

Above lists and libraries the menu is cut short and I see an edit button (which does nothing)

PS: While I am here ( I have posted this somewhere else too) I would also like to flag that the menu looks different above pages vs lists/libraries. Longer titles are just cut short, which certainly shouldn't happen either.
