Gas fees are "almost" always asked to be payed in TOMO in TRC21?

I posted this question on community support, but didn’t get any response. I have TCR21 Token with TOMO balance inside for the tomoz transactions. Transfer of token work sometimes perfectly especially on TomoWallet for ios even on TrustWallet or Metamask… But most of the time it needs some TOMO to verify transactions. Any Idea how to solve it?
