Thanks again for your help.
Sorry to bother you again, but I still can't find that quick settings tile.
So, I've got another issue that I'm hoping you can help me with. I accidentally did a long press on the floating button UI of my screen reader and selected the option to hide it. Now I couldn't bring it back. I tried restarting my device, but that didn't do the trick.
I know reinstalling the app is an option, but that seems like a lot of work. Do you have any other suggestions I could try?
(After numerous attempts, I finally found the solution. It turns out that the notification was turned off, which prevented me from seeing the option to enable it. Once I allowed notification permission, I was able to see the option and enable it.)
