how can I re-link my apps to play store? after installing custom rom and downloading most of my apps from pc and installing them offline, my play store account is peculiar, some apps I uninstalled weeks ago but i can still see on play store desktop, many apps are shown installed on play store mobile but not on desktop, and many unlinked apps.
so what can i do?
If your phone is rooted, then Titanium Backup app has a relevant feature that might work:


Tap the app you want to link from the list of apps on the titanium backup app
switch to the "Special features" tab
You will find "attach to market(forced)"


There's also an XDA thread about this.
