We use Sage 50 Quantum Account 2019 (Build 26.1.00.0229) on a Windows 2012r2 server.  We recently got the popup message below saying that our current version of Sage 50 will no longer be supported.  

I'm fine with upgrading, but the problem is that we use ShipGear, and ShipGear support told us to not upgrade yet to Sage 2020 because other ShipGear customers have been experiencing problems.  So I have been holding off in the upgrade.  Has anyone successfully been using Shipgear with the newest Sage 50 version?  Has anyone had problems?  

Is there a middle ground where I can upgrade to a supported Sage version that is not the newest one, but still compatible with ShipGear?  

Thanks for the info.
