I agree, never install any upgrades, everything might break, but to your point, look at the FAQ, this is probably the memory limit issue, but not that we see a reason why it should be connected to the upgrade.
Nakubaliana, kamwe kufunga upgrades yoyote, kila kitu ili kuvunja, lakini kwa uhakika yako, kuangalia FAQ, hii pengine ni kikomo kumbukumbu suala, lakini si kwamba sisi kuona sababu kwa nini ni lazima kushikamana na kuboresha.
