I didn't have any suspension issues with my ad accounts.
I worked for different companies and have different products. Like luxury clothing, food items, electronics and other ecommerce businesses.
The representative often asked me to increase the ad budget and make changes in the ad campaign to increase the leads or conversions. But I believe in old methods, so I stick to them and often ignore the suggestions.
They help one of my folks with the ads. My friend has a new Meta ads account for the brand new website (mobiles, cables and chargers) and he started a lead campaign and didn't get any results.
They helped him to optimise the lead campaign and also suggested him to run an awareness campaign before running the lead campaign etc.
But now he is getting better conversions and doing good.
