Please note that the v4 release line contains a bug where fee-enabled Interchain Accounts channels cannot be reopened in case of channel closure due to packet timeout. Regular Interchain Accounts channels (i.e. non fee-enabled) can be reopened. In order to be able to reopen fee-enabled Interchain Accounts channels, please upgrade to v5.2.1 or above.
