It seems that they lost Hagoromo's chakra specifically, which fuelled some of their powers. Sasuke's abilities seem far more time-limited now, but we haven't gotten a proper look at that.

Naruto probably doesn't have any more Biju chakra in him (other than Kurama), though he likely retains the "jinchuriki mark" of all 9. It's not clear whether he can call upon their chakra form wherever, or whether this is limited by distance. Its likely that Naruto needs to visit and ask all Biju again for their power, to re-enter his All-biju mode as seem currently in the ANime.

Truthseeking balls can be made (see: Kaguya's all-encompassing one) but TSB creation may be limited to Kaguya. Maybe Naruto hasn't used it enough to fully understand how to use it.
