Identified - If you're using Packing App things are still working fine.
If you're using Workstation App we have implemented a partial fix, which bypasses AWS. The fix will allow prints but will not read from the scale so weights will have to be entered manually.
TO TAKE ADVANTAGE OF THE FIX: Please close and reopen the Workstation App for this change to go live.
The team is still working to see if we can get Scales working on Workstation App using this solution. If we are able to do so we'll send another update.
Of course we are also awaiting a resolution of the AWS issue which will resolve this entirely and will require another restart of the Workstation App.

Identified - An ongoing AWS incident has been impacting performance for users of the workstation app all morning. AWS has confirmed the issue is not specific to ShipHero (there are also lots of people on Twitter complaining) and they are working on the problem.
However, we released earlier this year a new Packing App which you can download at https://app.shiphero.com/apps
The Packing App communicates between the printers, scales and shipping.shiphero.com directly, cutting AWS out of that step which means it isn't impacted by this issue.
Users of the Packing App are not impacted by this issue and we recommend you adopt the Packing App to resolve this incident and to avoid impact from inevitable future AWS issues.
