Agree with the frustration this change is causing. I am currently working with Esri support because the documented workarounds in the knowledge base article don't address sideloaded basemaps. The workaround is extremely awkward. I couldn't find any way to do it on an iOS device; I had to redeploy the entire tpk after making the change on a windows device (which is hours of file transfer) but the following does work:
1. Change the .tpk extension to .zip and unzip
2. Go to servicedescriptions >> mapserver >> mapserver.json
3. Search for maxscale in Notepad ++ or something
4. Find the one that is not = 0 and change it to 0.
5. Rezip using compression = 0 (store)
6. Rename the file extension
7. Redeploy tpk to device
Note that tthe Esri analyst I'm working with says there is currently no way in Pro to adjust this maxscale when you build the tpks or tpkxs - you will have to produce the package and then hack the file before deploying to the device.
