I have completed a compaign to test for one day and later on i created new ones and now it is still in preparing from so long , the first one got approved very fast i believe, in Google ads I never faced this , mostly within 2-3 hr, we get results, this fb ads is not at all moving from preparing state.
How to switch from postpaid to prepaid?
Is the postpaid is causing this issue?
I also checked my account no issues in support center, no ads suspended, account has no issues.
