Hi mmusman_CaseyTrees ,
In you want to maintain the history of the edits, you might want to consider using a related table (assuming that the geometry does not change). This way you would be able to calculate the number of edits using a simple Arcade expression o the related records of a feature.
As you have noticed when you have editor tracking enabled on the service, you will only have information about the create date and user and the last edit, but none about the intermediate edits. In Enterprise you would be able to use an attribute rule that records a record of what change has been done by what person and at what moment in time. This is not currently available in AGOL.
Maybe you can explain a little more about what type of data you have and why multiple fieldworkers are changing the data. This might provide some insight to your specific use case and could help to detect other alternatives.
