Puzzle 365: Double Nanro

Double Nanro, double the fun!
This new style is debuting here. This variation is a bit trickier than nanro. So, here is the complete set of rules:

Place two different numbers X and Y in each region, one number per cell, such that the region contains X instances of X, and Y  instances of Y. X and Y may change across regions. In the end, all the placed numbers must form a single connected group, with no 2x2 group of cells fully filled, and every number reachable from every other number through orthogonal paths. When two numbers are adjacent within a region, they have to be equal. When two numbers are adjacent across region borders, they must be different.

Edit: It just occured to me that there is a small ambiguity in the bottom-left corner. those who have solved the puzzle earlier, can use the new version below.

  1. There's an ambiguity in the top centre. There are at least two possibilities for the region with area 6.

  2. Yes, added a 5 in R1C4. That should resolve it..

  4. Oh no, it still did. 2 in R3C4 should fix it.
