Hello everyone. Yesterday, I opened a Google Ads account for my website and started advertising. It got approved around 3 hours later. When I typed the keyword constantly from my desktop, the ad didn't appear. But when I tried it from my mobile, the ad showed up. Then I tried from another phone, but no luck. Immediately after, I tried again from the first phone, but this time it didn't show up. Is there anyone who can enlighten me about this situation?
