Any suggestions which multicoin wallet to use instead?
You surely know better than to ask me that question. Here's my solution: Electrum for Bitcoin and Monerujo for Monero. Sell all your shitcoins for one of these two. 
And no Ethereum
I thought this could be the third one in the list too.Have you considered Unstoppable Wallet? Which is open source multi-crypto available on both Android and IOS.
For the altcoins and shitcoins Unstoppable wallet is the best, far better than the trust wallet.
