Hello,
I created an app based on a sharepoint list ("xx_MyList") with a column "Photo_Condition" formated as picture.
The picture itself is stored on the same sharepoint and referenced in the "Photo_Condition" column with its URL:

When the app is started, I load the content of "xx_MyList" into a collection "Loc_xx".
The photo is displayed from the Collection in the app with an image control as follows:
LookUp(Loc_xx,ElementNum=Loc_Index).Photo_Condition
where "ElementNum" is a column to index the items in the list and "Loc_Index" a variable in PowerApps to reference the correct item in the list.
For almost all users this method works and the image is displayed in IE, Chrome, Android and iOS.
For some users however, the pictures are not displayed. I could rule out the following:
- sharepoint permission: all users (even the ones not able to load the pictuers in the app) can open the images with the same URL in the browser.
- Devices: we tested with the affected users on different computers, browser and tablets, it works nowhere.
- Direct Adressing from Sharepoint List: if I am trying to load the picture directly from the sharepoint list with a display form, the photos do not load either
As i am not affected by this issue with my account/computer, this is very hard to troubleshoot for me.
Any idea what could cause this issue?
