Many newbies face a problem when connecting their wallet to 1inch, they can't find MetaMask.
What's the problem?
The problem is a conflict between two wallets Metamask and Phantom. If you use Chrome browser for example, then having two of these wallets, only one will be available when you connect.
Sometimes it happens that you want to connect Phantom and you have Metamask connected, this causes confusion.
How to solve this problem?
I would suggest using not only Chrome, but for example Brave as well. Leave Metamask in Chrome and Phantom in Brave. Use wallets in different browsers. This issue is not a 1inch bug.
This solution will solve your 1inch Support connectivity issue, and you won't have to ask support that you have a bug.
