App:
Spoiler
Check if the number is prime number, if not, run the 2 macros parallelly to find previous and next prime number.
Macros:
Spoiler
The 2 iterative macros are similar, just the difference in finding previous/ next number
I wasted so much time in simplifying the app and macros 😑 - just realize it is better to get the result first.

Very Fun Challenge.
Logic was to go with nested iterative macro. The inner macro takes a given number and divides it by all numbers less than selected number. Then checks the mod value for all of these. If only two records have mod of 0 the number is prime.
I wrapped the logic in an iterative macro that said if the information returned indicated the number was not prime - run it again with the number + or - 1 (so two different iterative macros one going up one going down).
Finally did a join multiple to the original number and checked for the closest prime number.
