Galaxy 8 suddenly not able to send texts to my particular iPhone
My mom lives in Indiana and has a Galaxy 8. Since Feb 12, she has not been able to reply to my texts or send me new texts. She can text other people with iPhones, and she can see/respond to group texts that include me. I don't *think* I accidentally blocked her, because my phone still lists blocking as an option for her in my contacts. Any ideas as to whether this could be something on my end?
iPhone SE, iOS 13
