Hey @ms0817
Thank you so much for reaching out the Klaviyo Community for help. I hope we can solve this together! I have a couple preliminary questions for you so we can troubleshoot the further.
Do you know if there is a specific email clients (i.e. Gmail, Outlook) that your mobile users are experiencing this error with? Is the facebook post embedded content in the template? Most major email clients (such as Gmail) view embedded content such as surveys, forms, videos, and other widgets as a security threat. These email clients will often strip out this embedded code completely and your recipients will not see your content feature rendered when they open your email. You can check the advanced reports tab of your campaign analytics and flow analytics to get a sense of how much of your customer base is opening your emails on specific email clients.
Are there any other Community members that have had this experience in the past, and how did you solve for this? If we collaborate together I’m sure we can find a solution since this seems to be inconsistent and hard to replicate.
