Offline Base Map not working properly

[AndreasKorsos]

I have created exiting data with a related table within a survey123 form and published it within a UTM projection. I created an Offline base map as a Mobile Map Package within a Web Mercator as instructed... but the mobile package isn't loading properly. I assumed (yes dangerous) that I would have no issues with differing projections but I am now wondering whether all data sets published must be web Mercator?  Am I missing something?

Thanks

Hi @AndreasKorsos,

Yes that is correct, all of the layers in the mmpk also need to be web mercator for them to display correctly in Survey123 field app. Currently the field app map viewer only supports web mercator.
