IOS 17.5.1 "hates my thumbs" but loves my pointer finger. (Touch this!)

I never had this "anti-thumb" issue with other vendors phones, Samsung, Google, Motorolathe past 10 years!

Sadly, company standard is the "Iphone", so I am "stuck" with this thing.

Iphone 15+ sometimes (more times than not) refuses to take "touch" from my thumbs.

I can touch it 2 or 3 times with thumbs nothing! I use my pointer finger; BAM takes the input. Its mostly hitting a back option, or selecting from the "tiny" upper side menu some apps have.

Outlook IOS add a contact with multiple accounts there is drop down to select which account to use..nope, not with a thumb.

I have made all sorts of adjustment in the "Touch" section with no good results. Doesn't appear to make one difference.

Any fellow thumb typers out there that found the answer to this issue.
