I’ve been having this issue for several months now and I‘m just now getting around to writing about it.
While writing my sermons in the Sermon Editor, I will have several sentences and bullet points completed, but then the slides on the left side will flash, disappear, then reappear. Meanwhile, some of my text (variable between a few letters to complete paragraphs) will disappear completely. This will happen about every 5-7 minutes or after several paragraphs of text.
Several months ago this happened on a Sunday morning as I was reviewing my sermon, and had to rewrite several paragraphs. The advice I received after that bug report was, essentially, “make sure you’re connected to wifi and click the sync button”.
Thanks,
David
