This has now happened twice. After beginning an event, all of my energy completely disappears, which is pretty detrimental to completing events with decent scores.
Also, I don't know if this has any correlation, but whenever this happens, a gray overlay is on my screen with an X in the corner but the overlay is subtle and nothing is in it. When I close it out, it spams me around 3 times telling me "there are no videos available at this time." When I close out of those is usually when the energy depletes.
How can I fix this? I have iOS 11.4.1.
