Hi Colin,
I removed the calculations from the one map shown above, but I still see the issue although almost feel like there could be residual funk possibly in that map since it is a save as of the original map. The layers included in the web map are hosted AGOL feature layers and tables. In additional AGOL reference layers like hybrid reference are included in the web map. The offline maps use side-loaded tile packages for imagery basemaps. I can open other 'live' maps and so it seems not specific to the one I mentioned above with the joined layer. I can reproduce with a couple of other offline maps that are generated from separate web maps but use some of the same feature layers w/ related tables as the screenshots below.
I also have an offline map that included calculated expressions that isn't having this issue using these same layers in a different web map.
So I'm not sure. Last week we were having issues with even be able to generate preplanned offline areas that I believe has now been resolved. I will try with an on demand for one of the maps having issues and see if there is an issue with that one.
These are preplanned offline areas generated in the web map settings.
Thanks for seeing if you can reproduce. So far its myself and another crew both using iPads that can reproduce. So a bit of inconsistency that I can't pinpoint the cause except I see it on several offline maps and pretty soon will have like 15 people using these maps regularly remotely. Although most are not viewing other live maps just using for offline data collection.
**I tried on demand downloads from the iPads on two of the maps that are having issues and both have the same behavior with screen going white/blank after viewing another map. Just wanted to update
thanks!
