Last week I added the RDZ RSSreader app which has been added to one of my pages and working fine. Today I have had problems adding apps - this one to another page within the same site collection, and another which has not been used across the site at all. Both have given me odd error messages:
"The app package does not support the culture en-GB specified for installation." Correlation ID: 522f329c-66d8-c00d-29c4-2978fd3e4227
I guess this is around installation settings. Today is the first day I've seen some changes where I can add apps in certain parts of my site but not others. Is this common, and can it be circumvented? I can't even uninstall this RSS reader now.
Anyone else with similar issues? Hardly worth integrating an app which solves a problem in one instance.... Nor one which only works in a particular country.
