According to TechFlow, BNB Chain officially announced that the Greenfield network and the MetaMask browser extension are currently facing compatibility issues, affecting some functions including the creation of storage buckets on Dcellar.

This problem stems from the fact that the MetaMask extension recently upgraded its middleware library to the latest version, implementing stricter EIP712 signature verification rules. The BNB Chain team is actively developing a hot fix to resolve this issue and is expected to release a fixed version on September 23.
