@eniolam1000752 I am unable to register delegate from a multisignature account

Steps:

• Register multisignature account
• Register delegate from the upgraded multisignature account

[ManuGowda]

@eniolam1000752 multisig registration is working.
delegate registration also works on regular account, but delegate registration on a multisig account stops at sign flow.

Also I see lot of TODOs can you please create a GitHub issue to address these TODOs

[ManuGowda]

• Information shown is incorrect (rank, last block forged, voters)

• Delegate is registered

• Delegates tab doesn't show my profile instead still shows register delegate

@ManuGowda I think the issue with the UI would be attended to by the validator tasks. I would align with @soroushm to see how these tasks can be modified
