SharePoint Hub Site Issue - Cannot Associate Sites to Hub Site

I have recently had a test communication site converted into a Hub Site on O365 SharePoint. I was then made a Site Collection Admin for the Hub site and another communication site I have been testing, however when I went to associate the communication site to the Hub Site, the option was not there.

When I click on the Settings Cog and go to "Site Information", I am only shown Site Logo, Site Name and Site Description. I should have an additional "Hub Site Association" option, but I haven't...

I was able to associate the site through PowerShell, but i don't want to request this every time I need to associate or make changes to the links with the Hub site.

Any help on correcting this would be greatly appreciated.
