I’ve noticed a rocket that respects my fuel priorities during a flight on Android, no longer respected the same priorities when I moved the craft file over to Windows. It’s an identical rocket with no changes made to the craft file.
Here's a craft .xml that exhibits this behavior, during the second stage:

On Android, the second stage tanks empty according to the priorities configured (a pair of side tanks at a time, with the nosecone portion of each pair always draining last). On PC, they all drain at the same rate.
My SimpleRockets2.exe version on PC is 2022.3.7.27451 and on Android the info screen for the app shows it’s version 1.2.109 (and Play Store says it’s up to date). This was reproduced on Nov 19, 2023.
Disregard, I suspect this was user error due to the setting on my PC remaining at the default "All tanks in set" instead of "Selected tank". Sorry about that!
