Follow these steps if you're connecting to Windows over RDP and you're taken to the Windows lock screen instead of your desktop:
Make sure NLA mode is enabled for your connection:
iOS / Android: Tap the blue "i" icon next to your computer's name in Jump and make sure the NLA option is ENABLED.
macOS: Right click your computer's icon and then click Edit. Then in the Advanced section enable Network Level Authentication.
After enabling NLA mode, try connecting again - you should be taken straight to your desktop.
