Due to compatibility issues, users of Coming 0.0.2 on IOS can temporarily not use the export keystore function.

If you only have the seed phrase (mnemonic phrase), you can use the Polkadot js extension plug-in to retrieve the Keystore file through the mnemonic phrase.

The operation tutorial is as follows:
