Quick summary

Inside the Jetpack Cloud search, sub-sites inside multi-sites will also show up. If the subsites contain a forward slash (e.g., /uk) then they can't be accessed. For example, the URL will be https://cloud.jetpack.com/activity-log/<main-site-url>/uk and the loaded page will be empty:

Steps to reproduce

1. Start at https://cloud.jetpack.com/
2. Log in and visit either the Dashboard or the Manage Sites tab
3. Make sure a subdirectory multisite is connected
4. Search for a subdirectory multisite
5. Click on one of the sub-sites
