both myself and itch have contacted the tax interview third party to find out why the interview that has no problems online is later flagged as not verified. That company stated 5 working days response time, but warned about it being longer due to COVID. Currently it’s 9 working days (13 real days) with no signs of life.
If I had to guess I would say this problem affects everybody outside of USA, but not everybody affected is bothered by it (they are happy to give a portion of their money away when they shouldn’t have to). I may be wrong about this.
