What are the most common factors that cause timeline delays in mobile app projects?

The most common factors causing delays include: scope creep from 'small tweaks' that break architecture, unpredictable app store review processes requiring multiple resubmissions, underestimating integration complexity with backend systems and APIs, the final 20% of polish and bug fixes taking 30% of the timeline, and lack of dedicated DevOps or deployment pipeline specialists causing handover delays. Changing requirements mid-development is particularly destructive to timelines.
