There should be the ability to create checklists from a mobile device while offline. The current state does not allow for a checklist to be created from a template unless there is an internet or cell service to the device. This makes the platform unusable to complete QA/QC workflows from remote locations or in areas with no cell/internet service.
The classic field application does allow a user to create a checklist from offline, this needs to be enabled in the new BIM 360 application.
