Auto-save time scale changes on gantt

What is the challenge?

• On gantt views, changing the timescale (3M, 6M, 1Y, Fit, Custom) does not save automatically. Users must explicitly click Save changes for the new timescale to persist.

• This is inconsistent with custom roadmaps, where the same kind of view adjustment is auto-saved.

What is the impact?

• The inconsistency makes gantt feel less polished and less predictable than other roadmap views.

• Users can believe their preferred view state was captured when it was not, creating repeat setup work and avoidable confusion.

• This is especially noticeable for customers who move between custom roadmaps and gantt and expect the same save behavior.

Describe your idea.

• Auto-save gantt timescale changes so they persist immediately after selection, matching the behavior already implemented for custom roadmaps.

• The preferred UX pattern should be that changing only the timescale is treated as a persisted view preference, not as a separate unsaved edit requiring an additional confirmation step.
