Thanks for all the work on Meta. I have a few questions (please excuse my ignorance on all things digital advertising).

1.) Why is ARPU so much higher in the US and Canada than the other regions?

2.) Why is ARPU continuing to grow despite Apple's rule changes - I would have thought if advertising becomes less potent via FB platforms advertisers would pay less not more?

3.) Should we be concerned that Volume of Ads (impressions) seems to have grown much faster than users - is that degrading the user experience and is limited?

4.) When does an advertiser actually pay Facebook - when somebody clicks or when they display an advert etc?

Any help on these or pointers to the answers would be greatly appreciated. Regards, Mike
