Power Automate's new designer crashes on complex workflow edits
Users report the new Power Automate designer crashing browsers repeatedly when opening complex workflows. The issue stems from high memory usage and affects both Windows and Mac users. The classic designer, an older version of the tool, shows no such problems and works reliably. No workaround exists beyond switching designers, halting editing on unfinished advanced automations.
Builders relied on the classic designer for steady progress on flows, even if its interface felt dated. Simple automations for emails, approvals, and SharePoint updates built up without crashes, letting non-coders focus on logic over troubleshooting. Now the hyped new designer falters under real workloads, exposing how Microsoft's UI overhauls prioritise flash over the stability beginners need for production flows. This regression traps users mid-edit, reinforcing that complexity breeds fragility in a tool already prone to silent failures.
Analysis
Microsoft's latest shiny update proves what we've known: chasing complex all-in-one flows in a buggy new UI is a recipe for stalled work and broken automations. Pin every flow to the classic designer today, then rebuild anything intricate as separate simple steps – that's how you get flows running months without drama.
