Apple Notes Blank

Sometimes when I go to my notes on my phone, the contents of my notes have disappeared. The only way I have been able to get them back is by going to my notes on my computer and editing the note where the content shows up.

To be clear - is it not a login issue. I am logged in to all of my accounts and I am able to see my notes. The title of the note is there, the subtext is there, but when I click the note, it is blank. Oddly enough, it will let me write in the note but with "invisible ink" so I don't see anything when I am typing, but if I leave the note, I can see gibberish in the subtext. See photos below.

So that image shows what I see even if I'm writing (of course there is a keyboard below). The second image shows what shows up after I write something, but if I click the note, I see nothing! Very frustrating when I need the content of a note when I only have my phone. I am not having this problem with my computer. Sometimes if I close out of notes, it lets me see what I'm writing again, but I still can't access the data on a note that is blanked out on my phone until I open it and edit it on my computer and they resync... its a confusing problem, I hope I have explained it clearly but if you need clarification just let me know.

I just got a brand new iPhone XR. Please help!
