UX extremly confusing in last updates... e.g cannot see which accounts has sepolia ether

Nobody has claimed this yet.

### What is this about?

Every update of MetaMask seems, at least for me, less intuitive than the last one.
A lot of people are migrating to Rabbit, and I think this might be the reason.

I can’t see the “See on Etherscan” button anymore.
Accounts don’t show the Ether balance on the selected networks.
Selecting networks is extremely confusing since it has to be done inside an account.
Since there's no exchange rate for testnet Ether you just see “No conversion rate available” message and an extremely small value.
i don't even see the address on the main page of the account...

NGL i understand that you are trying to on board users, but could you put a "dev" mode with all things i said that were always present?

No files, tests, or entry points are identified. Start by reproducing the reported account, network-selection, balance, address, and Etherscan visibility concerns in MetaMask 13.7.0; a complete issue would need a defined dev-mode scope and acceptance criteria.
