I created Ontology network on Metamask using details that I gathered from Web. I think this info should be right because several sites talks about the same things. Metamask approved all the info I input anyway.
After that there was an existing token called ONG shown on this network. I tried to add Wing token but Metamask could not detect any more tokens on this network. On the page Custom Token following page Import Token, I could see all other networks but not Ontology.
Why and how to solve?
Just follow the guidelines that @MAAMandang said, he's right, maybe you set up the wrong network in metamask, and that's what I experienced before op.
Although I'm not that familiar with the coins you're talking about because most of the time I'm just focused on the old and top altcoins even in that ontology network which is new to me.
