I appeal to the forum to solve the problem I encounter:
Since this morning I can't longer access the courses via the "Play Now" window. Nor can I respond to solicitations for sharing.
Actions open a white window and nothing happens.
In continuity I can't longer visualize the replay.
The malfunction occurred while I was consulting videos on my smartphone to accumulate credits, and an invitation was sent to me on my desktop.
Since 12 hours now I have been searching for the solution without success.
If any of you have an idea, or have been confronted with it, I am a taker of any idea.
