I installed and used WhatsApp for the first time last night to contact a friend who I suspect may be upset with me. I am trying to decide if they blocked and then unblocked me in WhatsApp. Here is what happened:
I started a chat with them (I could see their profile, but they had no profile picture and no status).
A few minutes after sending the message, their profile picture appeared and their status changed.
About 15 minutes later they responded to my message.
Immediately after their response I sent three additional messages.
After a few minutes I noticed that my three additional messages were not delivered (only one check mark).
After another minute or two, their profile picture was again gone, I could not see their status, and I could not add them to a group chat (I got the message "couldn't add xyz" when creating the group).
After about another 30 minutes, I got a response in WhatsApp and I could again see their profile picture, but it had changed to a different picture.
The three messages I sent after their response were never delivered.
My question is, can I say 100% that they blocked me after the first message and then unblocked me before they sent their second? If not, what could have happened? I don't want to ask this person if they blocked me and potentially make them more upset with me if they didn't block me.
