PLEASE HELP!!! EXCEL Formulas Not Working On Android?

I've been working on an EXCEL Workbook for a while and I even hired an expert to create some complex VBA Coding and Formulas for me. It works perfectly fine on my computer but I was extremely disappointed to find out that NONE of the VBA Codes or Formulas work when I open it on my Smartphone. It renders it useless since I need to use it on phones a lot.

The version of EXCEL on my computer is Version 16.41 (20091302).

The version of EXCEL on my Smartphone is Version 1.0.1 (16.0.13127.20162).

I assume both of those are the latest versions since they are the very first versions that appear when I bring up EXCEL in the Google Play Store and Microsoft Website respectively.

Could the problem be because my phone is an ANDROID SAMSUNG S20 and my computer is a MAC. Could that be the issue? If so, what is the way around this issue? Do I need to create one version of the Workbook on MAC for iPhones and another separate version on PC for Androids?
