I soaked it for 15-20 minutes then let drain. I always check to be sure the crown is nice and dry after. Although it is outside and may have gotten some water in it from the rain, even though it is in a covered area. You know how the rain can blow in Florida thunderstorms.
I think unfortunately it's already dead from crown rot. Has it received a lot of rain? I would use a much smaller pot and extra large bark for Phals in Florida, and I would pot them so the plant leans sideways, and the crown always drains.

You can try repotting. Put a few drops of hydrogen peroxide in the crown first, and let it bubble. When repotting leaves are likely to fall off. When bare-root put more peroxide into the crown. Repot sideways.
In the photo I see a plastic pot in which are bark and orchid roots. I don't see an outer pot.

For future reference, the benefits of powdered cinnamon is primarily as a drying agent. The evidence supporting the fungicidal effects is weak to nill for the powdered form. It is really really good at drying out tissue, so keep it away from roots.
