Jerry,
I've seen and heard of Notes not showing, but not of them staying not shown after clearing the cache (and possibly cookies) (should be done while only an empty tab is open, followed by closing all browser instances and restarting the browser). (Trying again, if you haven't, probably wouldn't hurt anything.)
I only had the problem once, and after clicking on either All Items or Unassigned Items (I forget which) and waiting several seconds, items started showing up again... It was weird. So you could also just try clicking around a bit to see if something trips...
My only other idea is that if you have access to the Gospel Library app (iOS, Android, Windows, or whatever), then you could delete the notes in the Gospel Library, sync to LDS.org and that should get rid of them. If you don't have the Gospel Library app or a device on which it will run (phone, tablet), you can try one of the following:
* Arc Welder - a plugin for Chrome that lets you run Android apps on a regular computer. Reported here:
https://tech.lds.org/forum/viewtopic.ph ... er#p138533
I have no experience with this, or Chrome, so I can't help with details, but it seems like it should be simple enough.
* Another Android emulator (or iPad emulator if you use an Apple computer). I know of a good Android emulator for PC on which you can install the GL app. Post back if you're interested and I'll provide instructions.
* If you're not game for either of those, but are willing to let a complete stranger log in to your account and attempt to delete all your highlights / notes, post back here or send me a PM. (Don't post your login here, just your willingness.)
FWIW: I can highlight verses in D&C 46, so it's not the section content that's the problem. (The heading cannot be highlighted, but that's true of all headings, lists, and the like - if you're trying to highlight the heading, let us know; but verses should work.)
Church tech support do not necessarily hang out here. There was a post in the past day or so about tech support getting a sudden flood of emails due to a glitch, so they might be slow for quite a while (mentioned in case you decide to contact them again, perhaps with a little different text so it's clear you're experiencing a technical problem that only a church employee could fix).
