When I add a public address for a Stellar account, the transaction history it imported did not include account merges. An account merge is where an account is closed and its remaining lumen (XLM) balance is paid into the destination account. The payment into the destination account is not shown in the transaction history for the destination account.
Thanks for reporting this @leighmcculloch. We’ll work on incorporating this as part of Stellar accounts that have been merged (deleted) can not be imported
