Not an Apple/iOS user anymore, but what I have been reading, 17.4.1 is pretty buggy. 17.5 is supposed to be released in May that is supposed to address some of the bugs in 17.4.1.
Unfortunately, due to Apple not providing signatures on older versions, not really recommended currently to downgrade to previous versions because the device may actually get stuck back on an older version and not be able to upgrade again. (so, not for the faint of heart to attempt the downgrade).
Not sure if you are interested but you can try the beta 17.5 if you want. (sign up as beta tester, then from your device should see the beta build as available). Of course, no guarantees there won't be more bugs in the beta builds. https://beta.apple.com/

Other than a possible buggy update, I think I would look under the Mobile Network connections of both phones (hotspots) and see if anything under the "APN" section stands out. I would also likely try a factory reset of the problem phone and see if that helps with any possible corruption.
