How do I show the updated changes to a form after I submit changes? I do not want to Navigate off the screen and come back, but I have not found an easy way to simply update the current form. Any suggestions?

This can be done with your Item property of the form.
If you currently have a variable in the Item property, then re-use that.
In the OnSuccess action of your form, set the formula to include:
Set(yourVariableNameHere, Self.LastSubmit)
If you have some other formula in the Item property, then set the Item property to:
Coalesce(yourVariableNameHere, <yourCurrentItemPropertyHere>)
Replace yourCurrentItemPropertyHere with whatever you have currently.
I hope this is helpful for you.
