it not done yet, don't rely on the airlock as a fermentation gauge.

Let it sit another week or two and then check the SG again.

Agreed, bubbling only means no co2 is passing through the airlock. At 1.021 it is probably not finished. I would also wait for a couple more weeks then bottle.

The yeast continue working after active fermentation is done by finishing the conversion of sugars to alcohol and cleaning up off flavors created early in the fermentation process.

Fermentation hasn't stopped, BUBBLING has...it's NOT the same thing. An airlock is a vent for EXCESS co2, it's not a fermentation gauge. You had two days of active fermentation, meaning lots of EXCESS co2 was being produced. But it's wound down now...that doesn't mean it's stopped...it's just slowing down as less sugar is still there to be eaten by the yeast. And as there is less sugar to be eaten, then the yeast are farting less....therefore there's no excess gass to need to be released. Doesn't mean they're not finished..

I agree to all of the above but would add the following:

Was this an extract recipe? A lot of extracts contain a myriad of less fermentable sugars and can create a less fermentable wort. This means that it may not go lower.

Second, you stated previously you use dry yeast, does that mean you used liquid this time? If so did you make a starter? If not you probably under pitched and had poor yeast health and at what temp did you pitch? These issues may also create attenuation problems in the fermentation process.

Then it needs more time but a a lot more info is needed now like mash temp and recipe as they will all play into where you should expect your FG to be and what it actually will be
