OneNote on ios blinking and keyboard goes away

I open OneNote on my iPhone 12, the line at the bottom of the screen blinks over and over and I cannot get the keyboard to come up and stay up. Every time I touch the screen it comes up and then drops back down. Anyone else seen this? Was going to call help desk but thought I’d see if this was also out here in the community. Thanks y’all. Took a video of it too. I’m tapping the screen every time you see the keyboard come up.
