Good question; unfortunately I don't have a good answer for you. Seems like a lot of supply chain issues across all industries right now. Maybe someone else in the community can get help..
Stock availability is internal to Visible team, so we cannot answer.
However i do suggest to try changing colors of the device if you are not peculiar about the color.
This is an anecdotal evidence, i changed colors and my transaction went through. As I wasn't peculiar about the color.
P.S: Please mark this answer as solution, if it helped you.
