Problem with receiving PV codes?

Hello guys!

I have a big problem with PV codes since yesterday. I tried to create an account on the phone number and then there is no problem, the sms comes normally. But when the PV block appears on my account (e.g. during follow actions) the sms does not come. I tried on smspva sites and on my phone number - with the same effect :/

Has anyone noticed something similar? Any solutions?
