I have problem with my hotspot no-one can join i reset my network settings but doesn’t work im with iphone 12 pro 14.6 version

I went into an iphone store and after spending about a half hour in a back room somewhere my hotspot showed up. I did not see how they turned it on. They would not replace my phone. I've not found another location anywhere else in the last month where it would come on. When it first arrived the hotspot would show up periodically but not stay on. Anybody else experience this problem?

Settings, control panel, add the icons you want

If the device you want to connect to hotspot is not on your AppleID then you need to keep hotspot screen open.

If the device is on the same AppleID as the hotspot phone then it will join without even a password.

Try turning on Maximize Compatibility

Sorry that was twaddle.

Tap and hold in the middle of the first block and it opens up

How can I get this screen result. Mine only shows the first two lines of icons, but without any word descriptions (or did you just photoshop those for illustration purposes)
