SWTOR Android App Serial key Illegal Character

Hello...

Earlier today, I called EA support to get my key generator removed, since it was lost during our apartment move. I tried using the SWTOR Android app. Whenever I enter the number 9, which is one of the characters of my serial key, it will give me the following error: "The serial number has an illegal character."

I have searched for a solution to this issue, and the only answers given so far is to:

- uninstall and reinstall app = doesn't work.

- install the newest version = doesn't work.

- triple check that I didn't enter the wrong character, since an "i" is similar to an "l" or a "1"... 😉 = absolutely definitely checked my serial key about a dozen times. I highly doubt entering "9" a different way will make a difference, because the error message literally comes on when I enter the number "9".

I already spoke to the EA customer support and he suggested the last one. He also suggested I use Google Authenticator, which unfortunately gives me the same issue. He said that no other customer has reported this issue. Yet, I have done a search here in the forums and found that this has been a problem.

Does anyone have an actual, real problem-solving solution to this issue?

PS: for those who don't know where you can find your SWTOR serial key, go to your SWTOR game properties in your Origin launcher.
