Tile Packages and 'new' Collector for ArcGIS

Question

Hello,

I've sideloaded a tile package (.tpk) to Collector (19.0.1; build 2609) on iOS (12.3.1) for disconnected (offline) use.  I've also configured the web map to use a tile package for the offline basemap by selecting 'Device will use a tile package it already has.' and providing that package filename.

However, I've encountered a couple issues so have the following question related to this:

*  The first issue is I can't access the tile package in Collector unless a map area has also been created.  Is this to be expected? The point of creating the tile package and sideloading was to eliminate the need for generating numerous map areas.
* Having created a map area, and now seeing the sideloaded tpk as a basemap option in Collector when disconnected, trying to open results in the following error: 'Basemap Unavailable. The spatial reference is not compatible with the map'. This error does not appear when using the same .tpk in Collector Classic; however, given the size of the .tpk (over 50GB) and our iPad storage capacity, copying the .tpk twice (once in Collector and again in Classic via iTunes) is not possible.

Any insight on these issues would be appreciated.

Thanks.

Anybody find a solution to the "Local Basemap Incompatible Issue"? (pic below).  My tpkx IS ABSOLUTELY matching the map spatial reference --> WGS84 Web Mercator.  Unfortunate other people are experiencing the same indiscriminate bug.  If anybody has ideas, let me know.  My order of operations was:

1) create a web map and add to AGOL

2) create a basemap using NAIP imagery and convert to tile package

3) "sideload" tpkx to my iphone

4) open map in collector --> add offline area.

5) Error strikes

I know the tpkx is being discovered, but the below occurs despite the matching spatial reference. Pretty critical functionality here that shouldn't be dysfunctional due to a bug.  Hopefully I'm missing something.  Help is greatly appreciated...

Hello,

Collector supports on-demand offline map downloading using the sideloaded basemap. After setting up the tpk (or tpkx, vtpk) name for offline use in the Web Map, and copying the tile packages to Collector Documents folder, I normally restart Collector first before using the tpk with map downloading.

Thanks,

Hello,

I abandoned the use of tile packages in Collector and started using map areas for disconnected data collection. I create the map areas in AGOL so field staff simply downloaded these to the mobile devices when connected. Unfortunately; however, only 16 map areas can be created for each web map. This is a problem for us because our 38 field sites are discontiguous over a very large area. As a result more than one web map exists.
