Cannot receive messages from some contacts
I just bought the LG Stylo 6. Software is android 10, version Q730QM10c. I can exchange messages with one of my contacts, who owns a samsung device, but not two other contacts, who own iPhones. They can receive my messages but I don’t get theirs. I do not have any blocked numbers so I am not sure what the issue is. I googled this issue but nothing helped.
