A transaction that remains in the mempool for too long often indicates a low priority fee. The metamask-extension smart contract is highly secure, but it requires precise gas parameters to function. Increasing the slippage tolerance by 1% can help bypass a transaction that keeps reverting. Sometimes the transaction is dropped by the network because the gas limit was too tight.
Most metamask-extension users find that a simple page refresh fixes the "stuck button" . Gaining a basic understanding of EVM mechanics will help you navigate faster. The error message you see is often a high-level summary of a more complex internal revert. Stay patient, as technical hurdles are often resolved quickly by the project's contributors.
