[Windows Mobile] mwalt2:
I am trying to make a 'hybrid' build using mostly the sense 2018 test packages. I am including the following:

"StartIconLoader_TEST"="2_5_20182114_0"
"Manila_Weather_TEST"="2_5_20182114_0"
"Manila_Twitter"="2_5_20161326_0"
"Manila_Stock"="2_5_20161214_0"
"Manila_Settings_TEST"="2_5_20182114_0"
"Manila_Photo_TEST"="2_5_20182114_0"
"Manila_People"="2_5_20161424_0"
"Manila_Music_TEST"="2_5_20182114_0"
"Manila_Message_TEST"="2_5_20182014_0"
"Manila_Mail_TEST"="2_5_20182014_0"
"Manila_Internet"="2_5_20143027_0"
"Manila_Home"="2_5_20161714_0"
"Manila_Footprints"="2_5_20161230_0"
"Manila_DocumentBrowser"="2_5_20143826_0"
"Manila_Core_TEST"="2_5_20182114_0_CFC"
"Manila_Calendar_TEST"="2_5_20182114_0"

I cannot get the Footprints or Twitter tabs to be displayed in sense. I have edited 26948339_manila as follows:

Does anyone know what I am missing to get the footprints and twitter tabs to be displayed? From what I have read, I think I have everything right...but I must be missing something. Thanks.

edit - Both twitter and footprints show up in ManilaFull.xml on my device. I can post the .xml if anyone thinks it would be useful to figure out why they are not being displayed.
