Acrobat for IOS does not show any Mark Ups

For years I have been marking up PDFs on my iPad. Now, all of a sudden, instead of being able to select text, underline or strikethrough, all I get is a mini magnification. This is useless to me, I can already see it, I want to mark it up. Has anyone else experienced this? Does anyone know a way to either turn the mini mag off, or at least turn the text selection back on?
