When I insert a brand-new 32GB SDHC microSD card (smallest memory size available at my local computer shop) into the slot on my new Roku 4 Ultra, it recognizes the card, prompts me to format, and then times out at 10%. Then it displays the message "Unable to format your microSD card for use with this Roku player." Card works fine on other device. Any troubleshooting suggestions?
Roku devices are VERY picky as to which cards work with them. Check old threads here to see which cards work best.

Btw, are you speaking of a Roku 4, or a Roku Ultra? There's no such device called a Roku 4 Ultra.
Yeah, I got some Rokus.
