Game won't stay open in background, reloads every time I go back to home screen

I noticed quite an increase in the frequency of times the game would unload itself while in background after the unity update. I tracked memory usage and their were obvious leaks for quite a while after that update but they have slowly improved and I won’t say it is back to normal yet, but it does seem to be improving for me. I play mostly on an iPad Pro so I guess this could still be a significant issue on some releases of android though.
