If you are holding AMC shares by close of business today, you SHOULD 100% get 1 APE share for every AMC share you have. UNLESS YOU SELL BEFORE THE 19th end of business day. You are NOT eligible for your APE share if you sell before you receive the share at the end of the 19th.
(THAT MEANS HOLD YOUR SHARES TILL THE 22ND IF YOU WANT YOUR APE SHARES.)
if they do NOT appear in your account on on the 19th. its up to YOU to call your broker and get it sorted out. ...
