I am using ArcGIS Pro 2.1.2. I have a number of template layout MXDs from ArcMap that I use without issue up until the other day.
I recently had a project where I create a map series. The map series came out fine. But after saving and moving to other projects, any time I create a new Layout using one of the templates, ArcGIS Pro creates a new Map with the name "Layer". The map is completely blank (no base map). When I go to the map view properties to switch the map view's connection to a map I want, the map view always zooms to Lat and Long of 0,0 and shows light blue/cyan Lat and Long lines.
Does anyone know how I might be able to fix this?
