Just succeeded in uploading a video of 48 MB via Jive Daily 2.22.0 on Android to our Cloud instance.
What kind of config did you experience the issue with?
No special config just using the standard JiveDaily app. We have experienced the issue on both Android and iPhone, using both WiFi and cellular data. Today I tested on iPhone with Jive Daily 2.22.1 and still having the issue.
I was able to successfully upload a couple of videos under 22MB but larger videos still always fail, no matter if they are shot from the phone (mov) or downloaded to camera roll from elsewhere (such as mp4).
I noticed the video is also gets compressed when I select it for upload. So if successfully published, its also a good idea to check the actual size on the desktop site by checking the download source size.
