iPad highlighting not working when trying to highlight more than a few lines!

I don't quite know how many lines... but once I try to highlight more than a few, it just doesn't happen.

I select a text and then click 'highlight' and nothing happens!

I've just tried this with highlighting 20 lines of text and it worked fine

Please provide some more details:

• is this on iPad or iPhone / which model?
• which mobile app are you using and which version?
• does this happen in just one resource or all resources? Please provide a specific example

Does it change if you store highlights in a different notes document?

Does highlighting work if you enable "swipe to highlight" in the View Settings (Aa) menu?

Or try killing the app and restarting it, or restarting your iPad
