Been running fb ads since a year, now suddenly no sales

[Keos]

Hi, I have been running ads on fb since a year, and up till April, all my ads were giving me a good 2x-4x ROAS. Now after the iOS 14 update, it’s all gone. No sales. 1 order a day. Really struggling here might need to shut the store. Please help.

Hi running into the same issue myself,  what type of targeting where you having success with?  We were using interest based and same thing has happened.
