I have 10 sheets which each have multiple cross-sheet references from other sheets. For the past year these sheets have functioned as designed, and all references (Vlookup and Indexmatch) have updated automatically without me having to even look at it. However, I noticed this past week these 10 sheets stopped updating automatically, and only refreshes when I manually open them. Ive tried adding automations (updating a helper column hourly, sending myself hourly refresh emails, and even adding a checkbox column which toggles on and off by the hour), none of which resolved the problem.
Any ideas on the cause of this?
note; these sheets have static rows, while the columns across update per the cross sheet references. No new rows are ever added- and the columns are fixed, with formulae in each column across which should refresh with data as it gets pulled from the reference sheets.
Any advice will be greatly appreciated, as opening these manually to refresh is time consuming and defeats the point.
Thanks!
