While we understand your point, the conversion of shares as a result of mergers is not among our supported services, as pointed by @Dougal1984 . Instead, eligible shareholders are currently receiving the cash equivalent of the new shares.
Nonetheless, this is a highly anticipated feature and we are working on implementing it, but we are not able to provide ETA yet.
Nice to know this “feature” is being worked on.
I think it should be made a priority though, as investors most people are looking at long term holds, and companies can merge at any time. It would be annoying to be a longterm investor for a period of years only to have your position closed with nothing you can do about it.
