Hello Anton,
We can make the earlier 2.3 version of the SDKs available manually. There is no automatic way that I know of to make more than the latest version available in SCN.
If you have not done so already, can you please raise messages for the glitches (with screen shots or steps to reproduce if possible) against component CA-VE-SDK-VEVM and I will try to address the issue in the next SDK release.
