Hi, I am working on developing an app using PosterScreen and VideoScreen. The app works fine on firmware version 6.2 build 3467 but on firmware version 6.1 build 5604, the videoScreen cannot play video, it returns back to the previous screen abruptly, and there are no thumbnails. I am using Vimeo Pro for streaming, and the images for thumbnails are not to the size as specified in the docs, (flat-episodic-16x9), but they just seem to be fine on 6.2 build 3467. Is this an issue with the firmware? and if it is, should I be worried about it ? if not, what could be the issue? I am sure the build used for testing is same and is not stale.
