Problem Solved!
The problem with Pages and Numbers was the iPhone model. Apple stopped supporting iPhone 7 Plus in July of 2023. Mine had not received any updates in a year. On 08/06/24, for a measly $929.87 I traded it in on a 14 Plus and the problem was solved. Incidentally; 7 Plus is the oldest iPhone that is acceptable for trade in, anything older and they will only offer to dispose of it for you.
7 Plus was running 15.8.3
14 Plus, as of, 08/06/24 was running 17.6
7 Plus had not updated Pages and Numbers since 13.1
14 Plus, as of 08/06/24, was running Pages and Numbers 14.1
For an extra $100.00 I even doubled the memory from 128 gigabytes to 256 gigabytes. Before the issue manifested itself I had only used about 85% of the available memory. During the crisis I deleted as much as I thought I could live without and got it down to about 75% usage of memory.
