Mine seems to be missing 2.0.39. I check Appworld and it says my FB is version 2.2.1.7
I upgraded to 2.0 this morning and my FB app did not seem to update and appworld is not showing i have 2.0.39 update available
appworld is saying I have 2.2.1.7
if I delete it, it says 2.0.36 is available, i choose "reinstall" and after it installs it says the version is "2.2.1.7" with no upgrade, my build of Playbook OS is 2.0.0.7971
