Yes, I have faced this issue before. It can be extremely frustrating when an ad account spends nothing after the initial two days of being active. The first and most important thing to do is to make sure that your ads are targeting the right audience and following all of Facebook's guidelines. If you're unsure if your ads meet these guidelines, you can use a tool like Meta Pro Support or contact a professional who specializes in Facebook advertising for help in making sure that everything is up to standards.
It’s also possible that there’s something off with the settings on your Facebook ad account itself that’s preventing your ads from running correctly. Make sure you check the bidding options, budgeting, delivery optimization settings, and other features within Ads Manager carefully as they can affect how quickly (and if) your campaigns will spend money. It could simply be an issue with targeting options or restricted content not meeting expectations which happens from time to time due to changes made by Facebook Ads algorithms.
Finally it could just be a matter of conversions taking time due either lack of optimization or too high bids for conversion events leading to low ROI/CPO ratios which means no budget spent at all; however this usually doesn't happen within 2 days so it's highly unlikely here.
Hopefully one of these steps helps resolve this issue so you can get back on track with spending money on successful campaigns! Good luck!
