ios 11 personal hotspot

iPhone 6s and iPad Air2 Wifi.

Before iOS 11 ….

• With Personal Hotspot turned OFF on my iPhone
• My iPad could see my iPhone in WiFi Settings under "Personal Hotspots"
• By selecting my iPhone it would
  • Activate the Personal Hotspot on my iPhone
  • (no need to manually get my iPhone out and start it)
  • Connect to the personal hotspot to give me internet access.
  • Deactivate personal hotspot on my iPhone when I close the lid on my iPad.

After iOS 11 (including 11.2.6)

• My iPad doesn't see my iPhone
• Unless I manually turn on Personal Hotspot
• Then it connects OK.

This is a hassle because:

• To use the internet on my iPad
• I have to first take the iPhone out.
• Press, press, press …
• And turn Personal Hotspot on
• Then, when I've finished on the iPad
• (Remember to) Get the iPhone out again
• Press, press, press…
• To turn Personal Hotspot off again.
• (No, I don’t believe in leaving Personal Hotspot on permanently.)

Am I missing something or has functionality been removed in iOS 11?

Tried resetting networking on both devices. What a pain that was, and didn’t bring this really helpful functionality back.
