This incident has been resolved - the Zapier Classic Editor is working consistently for all users.

The Zapier editor is still not working fully normally, and this may create delays in responding to Support inquiries. Our team's top priority is resolving this issue, and returning your Zap editor to normal. Sorry about this confusing delay.

We have discovered the source of the issue and we are working on a fix.

We have identified an issue where users are unable to navigate to steps in our Editor. Our engineering team is working on a fix for this and it should be released shortly.
