Toto ultramax I, e-max, slow draining

[KyivanRus]

Hi,

This is a video of my toilet’s slow flushing. Flush is 1.28 gal, e-max. Takes 30 seconds to drain.

Does it mean there is still a clog, even if it drains relatively quickly? It was a very fast 1-2 second drain before.. I’ve used this device with a lengths of 3 feet and goes all the way into the main drain hole freely. I can’t inserted it much (only maybe several/several+ inches into the siphon hole, but it’s probably because it just doesn’t fit(?)

Toilet is a few months old. Tank refills just fine (and quickly) after a flush. I’ve flushed like 40 times with the same result as in the above video. Please advise on resolution other than calling in a plumber (next step)

Clog or other obstruction. If not in the WC, then down in the drain. Have to pull it and check.
BTW, that is a less than optimal WC auger. General makes better with a bigger head.
If you have kids, it is a toy stuck in the trapway.
