We have several devices at different locations on the same account. I'm wondering if there is a way to organize the devices on the account by location. It appears devices are listed by the date they are linked.
No, there isnt - however, you could/should rename all the devices putting the location (or abbreviation/code) thereof in the name of the device, thus making it much easier to identify each one (especially when their are multiple identical models at one location).
E.g. "3810 - Beach - Living Room" or "4800 - Home - Master Bedroom"
You can also add custom location names, but there is no way to sort/list by location when managing linked devices at https://my.roku.com/account
