I have a SFP3 i5. After installing a few apps I encountered an issue where If i wanted to install one more app It will only be allowed to run in the background if I removed another app. It seems that the limit is 7 apps running in the back ground. Is this correct ? Or is it only for showing lockscreen notifications? What about updating live tiles? I cant find any information on this. It seems ridiculous to only allow 7 apps. Every app runs in the background these days.
