Hi Mark, A lot of times when a blockage comes back 2 or 3 days later it could mean that something was left inside the (toilet) fixture horn. When you said “you snaked” this line I hope you meant you used acloset auger and not a 1/4 ” “wire snake” I think you could one of 2 things going on here.
1- Either a Q tip or other foregin object causing this stoppageto re appear OR
2- Not enough water volume to properly get the solids to flow away. Try raising the water level to 1 ” below the refill tube if it is a tank and bowl Also consider using a large drop head Auger like the “General ” spring and wire type.
please keep me posted good luck.
