This may seem like a stupid question, but I do not see the Express 4K+ listed anywhere as a device that supports for 4k streaming on HBO max or Amazon Prime. Amazon Prime's supported devices seems very unspecific and although HBO's website lists specific devices the express 4k+ is not one of them. Can anyone with the product tell me whether it streams in 4k in those two apps? I know that HBO especially does not have a lot of 4k content, but I am still curious. Thanks in advance.
