iPhone 15 Pro Max hotspot constantly disconnects

I have an iphone 15promax, newest OS, unfortunately. I am so discouraged and can't switch back to android fro like 2 more years because of Verizon's awful trade in policy.

My PC, Mackbook air M1 and ipad pro constantly disconnect from my phone's hotspot. I think this is a feature and I hate it.

Like when I walk away from my crummy macbook and it locks, when I come back, hotspot is not connected and I have to go through all that again. JUST STAY CONNECTED FFS

I just moved in to a new apartment, the internet here is only xfinity. I'm trying to use my iphone for wifi for just a bit on my computer but still same problem, constantly disconnects and I can't get anything done.

I have chatted with applecare + for hours and hours and hours about my phone with no help. They are so useless. The thousands I have spent on apple products after I switched over in 2020 was a waste, I'm sad
