If you are not seeing the new Application Mapping channel, I suspect that you are on an upgraded appliance, and at some point a customised definition of the Applications page has been created, which is therefore overriding the current page layout.
Take a look in /usr/tideway/data/custom/reports and look for a definition in one or more of the reports definition files with a .xml suffix. It might look something like this:
If there is something like this, it is overriding the defined UI and hiding any product updates. There may be other page definitions too, doing the same thing.
The content of data/custom/reports is all customisation; if you don’t know what it’s customising, you could start by moving all the xml files somewhere else and restart the services, which will return everything to default, and therefore reveal the current UI. Then if necessary, you can selectively re-apply any required customisations.
We’ll investigate how we can at least detect and highlight any potential overrides like this during upgrade, though it probably won’t make the next release.
Here is the 8.3.x documentation for Custom Reporting.
