I updated to Oreo this morning. It won't let me flip through recently used pages like before I updated. I would push the square button on the right and I could flip through them. now the square button is practically useless. I tape the button and it does nothing. Only when I hold it will it let me use split screen. But I don't want split screen I want to be able to flip through pages. That was super useful Because I use my phone for work often. Flipping back and forth from PDF files and email. Now that I can't do it I have to go home and open the app which is way more work and super frustrating. Anyone else have this issue? Even Google support couldn't tell me if that was eliminated in the update.
