well when he was talking to sakura in the kamui dimension he stated that he could only transplant one of madara's Rinnegan because it was far to difficult to use both and that it was still to powerful of an eye it would stand to reason that it would be difficult to do so when being the shinju Jinchuuriki. also maybe he felt he did not need it because he was effectively immortal

No, he said he couldn't warp Sakura and himself back because it was too difficult with the tiny amount of power he had left. It nothing to do with the Rinnegan, where did you even get that??

Like Questionaredude said, the was never any reason given, other than it a excuse for him to weakened for the sake of the plot. He very clearly stated he couldn't do it, not that he didn't want to. That also becomes bullshit after Madara effortlessly teleported while a jinchuriki. So not only is it a half-assed attempt at depowering Obito, it isn't even consistent.

Obito specifically said that the Rinnegan is far to powerful. he said i also wasn't able to transplant the rinnegan into both eyes Even just this one left eye... i had lost to its overwhelming chakra and ability

and though i am not its original owner i have survived and made it all this way with just one eye

what he was saying is that the Rinnegan is overwhelmingly powerful. he survived by only transplanting one Rinnegan. before he had the shinju in him he was capable of using Kamui but after he was not shown using it so its safe to assume that it used to much chakra to control the shinju either that or he did not fill like he needed to use kamui because he was all but immortal
