Working Offline within Smartsheet



I am sure this has been asked before, but I cannot find a definite (more recent) answer to this question.

Is there an ability to work in off-line mode within Smartsheet? I am looking for the ability to work in Sheets (i.e. Project Plan tasks, budget financial input, meeting management, etc.).

The most common use case is travel (i.e. airplane, passenger in automobile). However, there are scenarios where internet service is compromised (i.e. warehouse buildout, remote areas with bad service, temporary outages, etc.) where this applies.

Please advise, thanks!
