If I import from TW to MM, still, I can see my crypto in TW? Because, as I am newbie, if I can't find my cryptos in MM or i am not able to use it, can I switch back to TW? Will my cryptos be there in TW also? Are they are in SYNC TW and MM, if I buy or sell in one wallet, it reflects in other wallet also, as recovery phrase will be same for both?
Everything is correct except this (highlight question)
All assets that you manage in one of them will be reflected in each other. Some situations might be true like your app crashes, you're using a lower version, or something like that (app error), then you can use another one instead. But in other situations, you can't even transact on both of them such as insufficient balance for gas costs, busy network, etc.
Some of the reasons you can't find your token:
- the token you received has not been confirmed on the blockchain
- you haven't added a token list to your wallet (as @Dread Pirate Roberts said)
- you have not added a new RPC network
