Why is FB advertising not working?

Question

Facebook

Hello. We have a group on FB. Yesterday I changed the name a little. Added a description of the product to the title. And on the same day she gave an advertisement from this group - website promotion. There were 4 ads.
FB sent me an email like this in response to the page name change:
Within the next 7 days, we will notify your Page's fans of this change, and they can let us know if they think the new Page name might be misleading.
During this time, any public associations your Page's fans have with your Page will be hidden on Facebook. We will continue to show the total number of people who like your Page.
The ad you posted didn't work. Those. it is approved, but there is no activity at all.
What can be wrong? Because of those 7 days?
I was also told that FB could consider such actions as spam. Those. name change and then advertising on a third-party resource. Is that possible? If yes, then what to do?

What is AdSense?
The ad didn't play at all. It hung active, but nothing happened. There was no user reach and no clicks, respectively. It must have been a FB glitch. Because last night everything suddenly worked and clicks went. Today there were about 100 clicks on the site.
