I’m wondering if anyone else has been having this issue?

I have an iPhone and have always saved FitnessBlender as a shortcut on my Home Screen and it works great. Recently though, I no longer have the navigation arrows at the bottom of my screen to go back. So for example, if I filter for certain videos and then click on one, I can’t go back a screen to the the list. I have to do the whole filter again. Or, if I open a post in community, I can’t go back to the main community page again. Instead I have to get there through the menu. My other home screen shortcuts still have the navigation arrows.

Does anyone know why this is happening and how I can fix it?

Thanks!
