Look at your home>settings>system>system update. It should tell you the date of last update. Does that date coincide with when the problem started?
The updates are notoriously unfriendly (and untested). Additionally, someone at Roku has something deeply personal against direct access to channels. They've held disdain at customers asking for numeric remote keys -- for years. The recent software update removed the favorite features. Also removed the ability to hold down the up/down remote button for continuous change, which was already slow. Now it's one press, one channel change. (They did this while adding 1000+ streaming channels to step through one at a time too.).
Since that update, people have increasingly been urging "use the enhanced remote, and change by voice." If a new update has broken voice recognition (for channel-changing only), that would speak volumes about Roku.
"People are often amazed at how much we’ve done with the number of engineers we’ve got." (Roku CEO Anthony Wood, Austin Statesman, Oct 4, 2019). "Amazed" is one way of putting it.
