That’s not error, it’s only warning to alert you about the DApp you are going to use may be able to transfer your funds without your approval. But that doesn’t mean all DApps are malicious.
I have enough bnb in my account. It is not about fees. As you can see on the screenshot, confirm button disappeared, only warning msg exist. Very annoying situation, i’m using metamask because of this issue.
Ok, if anybody have a same issue, here is the reason and the solution. Latest trust wallet version have a bug that swap button is invisible below the warning message mentioned on my first message. You just need to touch below the message several times than your transaction will be performed. Also swap button will be visible for a second.
