Aphria stock not transferred to Tilray after aquisition... how come?

I bought Aphria to take advantage of the Tilray acquisition and I have checked my ISA and I have been cashed out for a huge loss. Is this even legal?! I understood the NIO cash out when the stock contravened ISA law… but this is a simple acquisition and I am not sure you can cash out someone’s stock position without the client giving you instruction? I would appreciate a full explanation as to why… and is this a Trading212 standard procedure for Mergers and Acquisitions as I have a few stocks in my portfolio which I bought as I feel they are likely to be picked up by bigger companies. Many thanks
