I have 2 newish (received as Christmas presents) Roku Express+ devices (model 3910X). I use them intermittently - approximately 3 times a week, 1-2hrs. max per use. I unplug it after each use.
My wireless router does not broadcast my SSID. This has not been a problem for any of the multitude of devices on my network except the Roku Express+. Pretty much every time I plug in the Express+, it fails to connect to my wireless network. If I temporarily broadcast my SSID, the Express+ will connect. It will even maintain that connection after I stop broadcasting my SSID. However, it is back to square one once I am done, unplug it, and want to use it again in a day or two. Let me reiterate: the ONLY thing I change is broadcasting my SSID (no issues with weird password characters or anything mentioned in other topics).
This is an annoyance and does not seem to be working as intended. I have verified I have the latest firmware.
Is there something I am missing?

DBDukes, you may be right. If that is the case, then it is a step backward specific to the Express+. I had an old Roku 2 and Roku SE that had no problems with the hidden SSID, not to mention literally every other device I have that connects to my network. Other than manually entering the SSID for the initial setup, I have never (10+ years) had to do anything special for devices to connect to the hidden SSID.
Fwiw, I just hid my ssid and tested on my Roku Express and it connects fine after a restart and power cycle (unplugging/plugging back in), I also reset network settings on the Express and connected again as Private Network and it worked fine that way too, not much help I realize, but at least you can rule out needing some kind of special setting because it apparently should work as is, the only suggestion I can think of is to reset network settings on the Roku if you haven't already and turn off frame management protection if your router has it, it doesn't seem to play well with Roku in my experience.
