Hi, I’m trying to add my phone(+251 ***) number to my PayPal account, but I keep receiving an error message that says, 'That number doesn’t seem correct. Update it to continue.' I’ve double-checked the format and country code, and I’m entering it correctly. Could you help me understand why this is happening and how I can resolve it? Also, could you confirm if there are specific restrictions on the type of phone numbers PayPal accepts?
