Removing a bank stops new updates through that connection. An institution can include several accounts, so check the account list before confirming.
If the bank simply needs you to sign in again, use Reconnect instead.
Does this cancel Vylo?
No. To stop subscription renewal, cancel your plan. To close your account and remove its data, use account deletion.
