Whenever im installing a package by uploading the ui.content.zip from target folder onto the aem package manager, it is observed that the changes do not reflect in our aem instance on installation. Each time it needs to be uninstalled first, before installing a new content package.
Note - This question is for the envt's where we do not have a devops or provision for running autoInstallPackage present.
The ui.apps and ui.content zip folder from target are uploaded and installed.
It is observed that even force update does not add the updated content onto the nodes.
However, if the filter is the cause, you should have the same issues with the autoInstall profiles as you do with installing manually, so at first glance it would seem like that's not the underlying problem.
When you install via Package Manager, you can see the list of nodes that is changes (with A, U or D flags to tell you if it was an Add, Update or Delete operation).
What are you seeing with regards to the nodes in question?
Also: there are some know bugs with the Package Manager in the latest Chrome versions, try the same action via Firefox.
