I'm not sure if it's a bug or something I'm doing. I have the same module in the header on both app.
The main body jumps up into the header on app switching.
Hi @jason3w Hmm, I think I've seen this before 
Any chance you can share an export of your app so that I can share it with our team? If you export as JSON, the resource data will not be exported to us (just the components).
If you're not able to share the app, is that to navigation the only component in the "header" container? Is everything else in the main container?
Thanks so much! It appears to be caused by a bug with the sticky header setting:
I'll reach back out when it's fixed!
Ok, great. Thanks Tess
