Just logged into my computer using Microsoft Remote Desktop on my iPad to find this. I had tried earlier in the day when I tried using Chrome Desktop on my phone to connect - Chrome’s remote Desktop solution allows access outside of my home, while the Microsoft solution has a couple of router issues that, due to who owns the place I live at, can’t be resolved.
