Thanks for replying to my post as it confirmed that this disappearance of the daily trivia isn't because of the 14.5 OS update after all. Roku appears to be delaying this newest update to our older devices because of this update error that they're trying to resolve. My aging Ultra that's still on OS 14.1.4 also hasn't been updated since 12/19/24, so this is normal and our devices are still supported by Roku. I happened to check my Roku 3 which is very old but still supported -- around 13 years old, which is on 14.1, and this doesn't have the daily trivia on it either. After checking this morning, my Ultra, however, still has it, so Roku didn't remove it, and it appears to be an error that needs to be resolved.
Following those steps with the remote control below doesn't resolve anything; all it does is pull up the "Issue Report Tracker" so that Roku support can further help you, but this is no longer necessary since it's a known issue that is happening to many people including a couple of my Roku devices. However, if you want to see if you can bring that up in the event you may one day need it, try repeating those steps but do it slower. When I quickly hit those remote buttons, it didn't work for me either. Also if you still find you can't bring that up, try to aim the remote at the device. You also may have to rotate or remove and re-insert the remote control batteries (if your remote has removable batteries as the new voice remotes don't have that).
