Have you the “notifications” icon in the task bar at lower right? That should give you a mini menu where you can check things like network connectivity and apps.
On an Android device I spent hours trying to figure out why it was slow and using so much battery. Turns out the grand kids had several apps running I didn’t know had been installed.
Reminds me of my (late) father's iPad.
He would only access news sites. That is all, and only the ones I bookmarked for him.
He passed and I got his iPad and closed ALL his windows (he never learned to close a Window, seriously), I decided to clear the cache and history. . .found gobs of porno sites. Turns out my sisters boys (12-15 yrs old) were “borrowing” grand-dads iPad to access porn because mama would monitor their internet use while on their home computer.
