Age verification takes me to a yoti black screen

I tried Lebara support tab but it is not working, very poor

Sorry to hear you're having difficulties DaveK1, I suggest trying on both your mobile and wifi connections and if you continue to have issues give customer support a shout for further assistance.

Yes me too. Tried WiFi at work and it didn’t work - just a blank screen

Same advice as above NazleeM. If the usual age verification site is not working then contact customer support for further help.
