Used Siri dictation to send a test to my sister who is on android. She has never had an iphone. Upon confirming to send I immediately got an failure notice on imessage (blue). I opened up messages and attempted to resend. It reverted to a regular text (green) and went through. Shouldn't my iphone or siri know that its trying to send to a non imessage device? Seems pretty quirky? Also upon resending it didn't prompt me to send a text message it just reverted automatically. Ive also had other people on iphone send me messages that were "delivered" on their end, but I never received. Any insight is appreciated.
