Tomo Wallet transfer question

I had about 650 USD worth of TomoChain in a wallet on my Iphone app and I created a second wallet and tried to transfer assets from the first wallet to the second wallet- and everything has vanished. No longer in the first wallet and hasn’t appeared in the second wallet -0 + 0. Anyone have any ideas on wallet transfers within Tomo Wallet app (Iphone)?
Wallet address for second address was definitely correct- copied and pasted and double-checked.
First time I’ve used TomoChain but not first time using blockchain/crypto- I’m no expert but know the basics and this has baffled me- and left my account empty.
Any help appreciated.
