I contacted Apple about this issue: messages to Androids will send on iPhone only, not iPad or Mac computers after the latest upgrade to 15.3.2. Messages sent to Android phones on iPhone are not synching to Messages on computers. Are others experiencing this or have found a workaround?
It's working! Just was on Chat with Apple Support, and the steps below worked. I suspect I hadn't signed on to my iCloud account on my phone after the last upgrade, so text forwarding wasn't enabled. Once it was enabled, I enabled my computers which hadn't been done! I was able to text friends with Androids using RCS on my computers.
1 Go to the Messages app on your Mac.
2 Choose Messages > Settings, then click iMessage and make sure you’re signed in.
3 On your iPhone, go to Settings > Apps > Messages, then make sure iMessage is turned on.
4 Tap Send & Receive, and make sure the Apple Account listed at the bottom is the same Apple Account you’re signed in to on your Mac.
5 Tap , then tap Text Message Forwarding.
Note: If you don’t see Text Message Forwarding, make sure you’re signed in to the same Apple Account on both your iPhone and your Mac.
6 In the list of devices, turn on your Mac.
Thanks for coming back and sharing the solution.
Messages on computers no longer sending to Android
