Your not alone if you are feeling overwhelmed, helpless, and defeated. I don't think any of us know what to do, although some of us have enough focus to just keep doing what we've been doing to maintain the metrics that we have.
Seeing as we were told we had a 30-day grace period to 'do something' about it, which might have made us assume something could be done about it in that time span, one of the things that I've been looking out for on these threads since the announcement is if anyone was able to do just that. I haven't seen anyone mention anything other than decreases in Success Scores, but I could have missed something.
