@semlovessims There's no current fix for the EA App version of Sims 3. I do want to point out that CAW and EIG still work just fine with a disc install, and with a Steam install once the necessary registry edits are applied. That would of course involve giving more money to EA, directly or indirectly, unless you managed to find a secondhand disc copy of the base game that didn't require Origin to manage the install process; that means any disc manufactured prior to September 2012.
Other than that, there's unfortunately nothing to share, other than that EA is aware of the issue but probably isn't going to bother to fix it.
@puzzlezaddictIt also works with Origin installs IF you manage(d) to wrangle that possibility. There are those who blocked the EA app from installing and there's a new dirty way, as well (found on Reddit and Twitter).
