Hello and welcome,
Unfortunately, the challenge was a special case where we could change your home and bonus locations. Home locations, once set, cannot be changed, and bonus locations typically can only be changed once every few months.
Now, you do still have some time to change your bonus location, as we were given 48 hours after the challenge ended to change it again. However, being that there isn’t much of a backlog due to the challenge, it’s hard to say where there may be a good deal of edits that need to be cleared out.
If you do still want to change your bonus location, you have until April 24th at 5:00pm PDT, which is 00:00 UTC on April 25th. What you may want to consider is larger metro areas, as these tend to have the biggest backlogs when there are ones.
