It is now possible to use the Saganworks app if your mobile device is offline. To make sure it works properly, make sure to visit the Sagans you want to edit (as a builder) or view (if it is yours or someone else's) prior to going offline. This ensures that your work is cached and available regardless of your connectivity.
Once offline, these are the only Sagans you can visit. Any Sagan that you do not visit prior to going offline will not be cached, thus unavailable during your period offline. The map view will show all Sagans, but do not assume they are all available.
You will know you are offline because a yellow cloud with a line struck through it will appear in the upper right.
You will not be able to add documents and files from your app during this period, but you are able to interact with and download KIs in the available Sagans.
If you are viewing another builder's Sagan, you have all the same functionality that they allow as well. Again, you only need to view their Sagan before going offline to ensure you have this available to you.
