Maximum number of hub navigation nodes?

[Alex Grover]

I'm building a comprehensive navigation in a hub site. Around 230 total nodes. From my testing I've noticed that the hub nav disappears once you go over around 170 nodes.

If I load the web's TopNavigaitonBar collection and their children, all the 230 nodes are there. They are also visible on classic pages. Happy to provide screen grabs if required 

Then if I remove enough nodes the Hub navigation eventually reappears. I can't find any documentation around number of supported nodes for Hub navigation. Has anyone seen or experienced this before?

In this thread here https://techcommunity.microsoft.com/t5/SharePoint-AMA/Maximum-number-of-sites-associated-with-a-Hub-...  @Mark Kashman says there is no limit. 

 Can you provide the screenshot so we can look at it? Thanks

We have the same problem.

We're testing a hub menu with about 360 nodes, mostly at level 3. Level 1 has 6 items. It vanishes about half way through.
