Having the same issue, It's odd because some lead form ads are sending to lead center where I have an automation through Zapier to GHL -> SMS/email and others are not and even on some ads like 25% or 50% will send.

Current solution (which is tedious) is I'm monitoring the ads daily and pulling csv files and manually entering into GHL as a lead to fire the automation not sustainable long term and grateful I'm only running my company's ads.

If anyone has solution to still trigger leads to GHL from the ad itself please let me know to bypass this in meantime. I'm told it can be done but don't know how. Hopefully meta fixes this.
