I've recently upgraded AEM 6.2 SP1 CFP 14 with the latest CFP 17. After upgrading and restarting AEM editor mode is not responsive. I'm not able to edit/add components or even use header's coral panel.
Another found issue is: portals' cloud configurations are not listed on miscadmin#/etc/cloudservices on author mode thus I'm not able to activate any changes.
Are there any prerequisites needed when switching from CFP 14 to the latest one? I've not found any relevant information in release notes.
