A particular phone number which is important to me says its now blocked but when I go into the blocked settings it doesn't say this number is blocked. I can call the number fine but receiving calls doesn't even give me the option to take it and if they don't leave a voicemail it doesn't even notify me that they have even attempted to call me
@sniff23: Is the number saved in your contacts? If not, please try heading to the Phone app > Tap the 3 dots in the top right > Settings > Block numbers > Block calls from unknown numbers, and toggle this option off if it's active. Tap the Back button > Caller ID and spam protection > Block spam and scam calls, and toggle this option off if applicable.
If the number is saved in your contacts, please head to the Contacts app > Select the relevant contact > Tap the 3 dots in the bottom right, and check to see if 'Unblock contact' is available for selection in the pop-up options. Let me know how you get on.
