Hi All.
Recently I've made an app to display current and upcoming birthdays and employment anniversaries.
However I've noticed that I am getting the correct order while my co-workers are getting a seemingly random order - nevertheless they see the same order as the other co-worker (I checked with 2 of them)
In a bird's eye view this is the app and how it works.. i'll just detail out birthdays (since anniversaries works the same way - the problem will likely be the same aswel)

Strange thing is, both my co-workers see the exact same order which doesn't make sense to me - if it were to be random why are they seeing the same?
How this works:
The Datasource list:

It get's stored into a collection on app OnStart() like this:
ClearCollect(
UpcomingBirthdaysThisYear,
Sort(
Filter(
Medewerkers_Lijst,
DateValue(Text(Month(Geboortedatum), "00") & "/" & Text(Day(Geboortedatum), "00") & "/" & Text(Today(), "yyyy")) > Today()
),
DateValue(Text(Month(Geboortedatum), "00") & "/" & Text(Day(Geboortedatum), "00") & "/" & Text(Today(), "yyyy"))
)
);
ClearCollect(
UpcomingBirthdaysNextYear,
Sort(
Filter(
Medewerkers_Lijst,
DateValue(Text(Month(Geboortedatum), "00") & "/" & Text(Day(Geboortedatum), "00") & "/" & Text(Today(), "yyyy")) < Today()
),
DateValue(Text(Month(Geboortedatum), "00") & "/" & Text(Day(Geboortedatum), "00") & "/" & Text(Year(Today() + 1), "yyyy"))
)
);
ClearCollect(
AllUpcomingBirthdays,
UpcomingBirthdaysThisYear,
UpcomingBirthdaysNextYear
);
Shortly put the code takes first all the birthdays that are yet to happen this year sorted first upcoming to last upcoming + birthdays coming up next year sorted first upcoming to last upcoming and stores those 2 collections into a new collection.
The first thing that came to my mind was to check whether the newest version of the app is live - and that is the case.
If anyone has any idea what could be the cause of this i'd greatly appreciate any input!!
Kind Regards
