Adwords campaign not working?

Question

Google Ads

Guys, hello! Moved the campaign from direct to adwords using the "teleport". All settings seem to be set, advertising is on for 3 days, then there are no statistics, no impressions. What could be the problem?
ps in the morning it showed notifications that there were no ads in all groups, although it all seems to be in place, now the notifications are gone, but the result is the same - advertising does not go.
Tell me where to drip, thanks!
