I have been using Graphene since August or so of last year, everything has been great and it is truly an impressive feat. In the last week or so Google Fi keeps complaining to me that it is not fully activated and when I try to finish it, it errors out with code B053. I have tried clearing cache and storage for the Google Fi app, removing the Google Fi app and reinstall. This is running on a Pixel 6 Pro for reference and everything is up to date as of this writing.
Unfortunately none of these have resolved the issue and I was hoping someone had some insight. If there is any addition information I can share to help with a clearer picture, please let me know.
Thanks for reading!
