Why can't I edit block in any flow and campaign?

Hi there @Mike41854651, 

Thanks for sharing your question with the Community! Happy to help! 

In my experience, this can be causes by various reasons but is typically a browser issue. I’d suggest pursuing these possible routes to find a solution : 

• Navigate into your account and try editing your blocks via Incognito mode
• clear you cahce and cookies in your server history
• Logging out and back into your Klaviyo account
• Double checking that your ad blockers, anti-viral softwares, or network filters/firewalls aren’t preventing these pages to load
• Ensuring that the browser you are using is up to date

However, I can see that you still have an ongoing conversation with one of our amazing support team members. They will be able to pinpoint the issue for you so I would encourage to keep working together to find the solution! Additonally, I’d encourage you to check out this Community thread of a peer who had a similar issue to gain more insight.

Thanks for participating in the Community!
