Fake id to be blocked

Hello,

I checked my blocked accounts list of my snapchat account. The blocked accounts position on the list changed without me blocking or unblocking any of them.is it normal or should i be worried that my account is hacked?

If I change my number in WhatsApp, will my blocked contacts realize it after unblocking them?

Hello, so my problem is that my firewall seems to be blocking my internet connnection, I have the follwing message :

Security or firewall settings might be blocking the connection.

Your Internet access is blocked.

I have a perfectly fine internet connection and when I diagnose my connection problems it tells me I have a good internet connection but mentions that my firewall settings might be blocking the connection. I have spend hours stressfully trying to find out the problem but I just can't seem to find the solution would somebody a bit more experienced with computers be able to provide me with some help please it would be greatly appreciated,

I have sent a text message with a request for notification of delivery. The message has not been received as the phone is turned off. Will notification be sent when phone is turned on? Is there a time period that is used, for example, if the phone is turned off for 24 hours, there will be no notification sent to me that it was received?

thank you! jennee
