Hello,
To the best of my knowledge, while you can create a 360 degree OIL in the ArcPro 3.2 update- you cannot view the imagery. The best solution is to download the the ArcPro toolbox for managing oriented imagery which can be found here.
Please note: When using the toolbox, you are creating an OIC, not the OIL. OILs are not yet supported for viewing 360 degree imagery.
