Question

Why is the Klaviyo so PAINFULLY SLOW pretty much all the time?

I am on 3TB internet with the fastest equipment. Klaviyo is SOOOOO SLOOOOW! I am waiting all the time for it to do pretty much anything. It must be the browser interface that lacks so badly. Speed matters folks. Figure out how to do it better and FASTER!

Is it always like this for you? We experience a ton of intermittent Klaviyo errors–occasional slowness, whitescreens, UI oddities, etc. but it generally resolves over time and goes back to normal. And normal is not lightning quick, but not too bad. What’s your “normal”? Is it always slow?

Also, are there any screens that standout for their slowness? From my experience opening flows with a lot of nodes is slow, and sometimes opening/editing templates. Curious if there are any particular pages you experience problems with?

 

All the best,
