Argyroderma not improving since arrival..
Since the arrival of my mesembs, the Lithops and Pleiospilos are doing quite well but this is the only plant so far that I have not been able to figure out. While it's only been a bit over a month, but when it arrived it had a bit of wrinkly skins and also a few split from possible overwatering on the sides. I was told to leave it be and keep it away from sun and without water for at least a week or so and I've done that.
Around 2 weeks in I gave it a very very slight splash of water, and maybe a few misting and that's it. But it seems like it's wrinkling even more now, with a few more split spots as well! I feel like it's sending me a mixed message of "I'm thirsty" and "no more water!"... and would love some advice from experts.
Day of arrival:
