We have recently created our Intranet using SharePoint on-line (with hubs and sites using out of the box navigation).
However when logging into the mobile app on an iPhone we are experiencing issues with the navigation. The navigation options take you to the desired sites/pages, but when you click 'Home' on hamburger menu, then click on a navigation option (goes to the correct place), but then if you press back, the navigation destinations seems to be out of synch, so when you click on an option you end up somewhere else on another site.
It is also odd that once you are within the intranet you lose the ability to see the standard options at the bottom of the screen (News, Find and Me).
All of the above appears to work as expected if you browse the Intranet through Safari (the browser).
The issue is only observed on the SharePoint app downloaded from App Store.
Note that we have not got Global Navigation switched on our Tenant.
Anyone else experiencing similar issues with the App?
