I switched to android, but all imessages are going to my mac.

I temporarily owned an iPhone and recently switched back to android. I have disabled iMessage. Yesterday I sent someone a message from my Messages on my mac and now I can no longer receive texts from them. All messages they send are iMessages that aren't being sent to my phone. But any text I send goes through just fine.

I don't know what to do, and I would appreciate any help you can offer.

If there is a better sub for this question please let me know.

Thank you.
