Lesson Material Corrupted--Reactive Programming Model

Reactive Programming Model

I downloaded the Lesson Material but unable to open it. The file size remains 0. I refreshed the webpage and downloaded several times but still no help. 

Hi Wenlu Xu ,

Try to download to switch Cross-platform tab .

its working .

Thank you the cross-platform one works! 


It looks like there is some issue or changes/upgradation going on for the contents available under Training menu. There are some other issues logged by other team members as well and the issue has been already reported to OutSystems team. Please refer these links.
