Lost Content

[B_in_Dallas 0]

I suspect I had an overly paranoid uBlock Origin subscription in play (Firefox), and I ended up losing content in three notes via the web this morning.  One was just a grocery list and can fairly easily be reconstructed, but two others had some information that's important to me.  As I loaded the page I saw the note was empty (title was intact), so I clicked another note to see, and wiped it in the process.  3 in total.  I pulled EN up on my phone (Android) and could see note contents initially, then it sync'd and it was all gone.

If I upgrade to a paid plan now, will any of the note history be available for me to restore, or am I SOL?  I have no support as a free customer, so I'm posting here for advice.  (I tweeted support but don't expect to get a response)

Thanks in advance for your help!!
