Thanks for all the suggestions. I'll now give the update.
Strangely, when someone removed the stopper for me, the drain no longer was slow. Apparently, it may have been too low to the opening. It was raised, and so far, it has been draining properly.
Don't know if it will stay that way. I was going to get the suggested Enforcer liquid and try that. If it slows again even with the raised stopper, I shall do so. I first wanted to try the YouTube suggested baking-soda/vinegar recipe. I had heard of that before, of course, but I was going to try the exact amount and the advice to wait for a certain amount of time until boiling water is introduced (usually I would put a ton of baking soda and vinegar down the drain and immediately follow with boiling water, and it usually didn't do much).
I hope it stays this way. Another YouTube video -- thanks for suggesting to engage YouTube, Dana -- mentioned that the stopper and the thing that holds it in can get junk on it. Did simply moving it dislodge something? I don't really know. I just hope the drain functions properly from this point on.
