Title: Sheet tab order reverts to creation order when reopening file
Description: Sheet (tab) order does not persist after saving and reopening. When I manually drag tabs into a custom order, closing and reopening the file resets them to chronological creation order.
Steps to Reproduce:
Create a spreadsheet in Proton Sheets with multiple sheets/tabs (e.g., "January", "February", "Summary")
Drag tabs into a custom order that differs from creation sequence
Wait for autosave to complete
Close the file
Reopen the same spreadsheet
Observe: tabs are reordered to match creation sequence instead of the arrangement I set
Expected Behavior: Tab order persists across sessions, the same way cell data does.
Actual Behavior: Tabs revert to chronological creation order on reopening.
Impact:
Tab order must be rebuilt every time the file is opened
Disruptive during collaborative work sessions
Most reproducible after duplicating a tab and then repositioning it
Workarounds Attempted:
Waiting for autosave to settle before navigating away
Hard refresh and clearing site data for docs.proton.me
Building tabs in target order from the start (partial relief only)
Environment:
Browser: Brave (Windows), latest stable, Shields down
OS: Windows
Account type: Proton Unlimited
Platform: Web app (docs.proton.me)
