We are a diet/weightloss business based in Eastern Europe and have been successfully running FB ads for 3 years. However, we have experienced a sudden dip in ad performance - Ads don't launch, don't spend, reach is very very low. For about 3 weeks we have been trying to fix this issue.
We have now switched to Business manager without any luck.
Contacting FB several times resulted in very little insightful response from their end.
We require a very experienced FB Ads manager, who is currently managing campaigns to help us get back on track, and perhaps improve further.
This would involve and initial 30-60min Skype call, plus potential strategy plan from you.
