Windows 10: One note contents gone

I've been on chat iwth Microsoft about this and I've posted the problem before, but still no solution.
I log on to Windows One note as per normal. All seems OK; my notebook appears (Allan's Notebook) along with the contents, but only briefly and greyed out; then disappears. I have two stage log in enabled where the log in is enabled by Authy code (six number code). All appears normal, but it just will not load completely; just greyed out contents for a second and gone. There are files on there that I would relly like to get access to.
They are not in backup on One drive. They are obviously there, but won't stay visible.

:)

 

Why did the startup window get cleared?

I didn't missed any step, the list was gone and gone , even after using lot of programs the programs were not listed in that list.

 

Unable to "get media content" from text messages.

My Nokia 920 on ATT was showing this exact error "getting media content" for a long time... finally spent a chunk of time attempting all suggestions above...

FIXED:

• Created New MMS APN (steps here: Setup Guide for AT&T APN Settings Windows Phone & MMS Settings )
  • still didn't work
• Deleted MMS APN
• Group messages started working!! No more "getting media content", it just shows up.

Note: Didn't help

- WiFi on/off

- Back up text on/off

- Group text on/off

- Data on/off

 

When I enter the event in the note pad and then close the screen, when I come back to the note pad the entries are all gone

Hi,

whenever we type any content in notepad and close it without saving then all the contents will get erased. To get the contents saved in your system you need to save the files.

Follow the steps below and check if it help.

• Open the note pad, enter the details.
• Click save on the top left
• Give a name to the file.
• Click on Save button. The files will get saved in the particular location.

I hope the information is helpful.

Thank you.
