Like I said in my earlier posts, No.
You said "the Addons section of the sim", which is not very clear, since there's an "Add-ons" menu, and another Add-ons sub-menu in the OPTIONS menu. That's why I had to ask because, depending on *where* it's actually missing, the next troubleshooting steps would be totally different.
I'll clarify better:
- If it's missing from the OPTIONS->Add-on menu, it will *surely* miss from the "Addons" menu, and this usually indicates a problem with a failure to create/update the add-on.xml
- If it's present in the OPTIONS->Add-on menu, but it's missing from the main "Addons" menu, it's likely a totally different issue, usually related to antivirus and/or missing system libraries.
So, which is your case, exactly ?
