I’ve reconsidered my review and realized that I mainly evaluated the support rather than the product itself. In hindsight, that was unfair and probably also due to my impatience.

The server-side error happened to occur during the Chinese holidays, which was simply bad luck. Staffing shortages can happen during such periods (or due to illness), and that can unfortunately delay responses.

Therefore, I’d like to revise my rating: Diaflow as a product is fantastic. I was able to work very well with it and was genuinely impressed by its capabilities. Looking back, I regret returning the deal too quickly, and I can easily imagine purchasing Diaflow again, probably even at the highest tier.

Original review:
I initially had high expectations for Diaflow (AppSumo Tier 4), but right now it’s practically unusable for me: the Tables module is completely blocked. Every time I try to create a table—whether manually or via CSV import—I consistently get the server error “Oops! Something went wrong on our side”.

The real issue, however, is support: I’ve received no response to my requests (email + form) for over 14 days. Without tables, a core feature is missing, and without support there’s no indication of a solution.

Positive: Automations are extremely easy to create.
Negative: The core feature (Tables) is broken for me + support is unreachable. No feedback at all :(

As long as it doesn’t run reliably and support isn’t reachable, I unfortunately can’t recommend Diaflow. I returned Diaflow.
