has gcn gone ex

from what I can see on my trading platform GCN has not gone ex

now GCN on their last announcement did not put down an ex date,

speaking to computershare they are handling book closing and only book closing

so the question is, and GCN has made it clear they will only go by book closing and leave it to computershare, when can you sell in order to still qualify for the P1 shares.

if anyone who has sold today, will they be entitled to P1 shares,

if you sell today you don't get the money till 3 days, but will you still own the actual shares, this is something the broker should be asked,
I know I asked mine but seems I cannot give the results of that ruling.
