Sent USDT from Houbi on Heco successfully but Metamask not showing

Added heco-mainnet and usdt already. Sent 1587.7488056 USDT from Huobi using Heco network. Houbi account shows that the transaction is successful. But MetalMask wallet not showing.

MetaMask has zero USDT

feeling strange. Pls help.

Hi Do34 :grinning: you tried to add the token manually? Click Add Token and Custom Token…

Yes,i have added the token manually

I found that the USDT can be found using Tokenview, the USDT arrived at my wallet address.
But both Metamask on Chrome extension and on my mobile phone still shows zero balance.
Do you know how to fix it?
