The instructions for the photo scavenger hunt were on all the junior high kids’ screens, shared using a Zoom function I’ve employed weekly since March with no difficulty. But a smudge appeared on the screen, and then another. I asked my co-leader if she saw it. She did. As if granted permission, then, the smudge spread out over the entire slide as a dark scribble, obscuring the instructions from view.
Clearly, somebody was hijacking the slide. “How is that happening?” I asked. One student replied in the chat: “Must be a glitch.”
Uh huh.
I suddenly recalled this experience from 2014:
They’re always ahead of me on the technology.
YoRocko! 
Ugh! To everything there is a season, and a time to every tech problem under heaven? Best of luck!
