I did a search on visiting neighbors because that is what I am concerned with - and didn't find any information regarding the update. It never occurred to me search for "browser update" as I am using the same browser on my laptop for both beta and non-beta. I noted the wonderful change to the non-beta visits in mid-December right before we left on vacation (while on vacation mobile app only). I anticipated that the same upgrade would have been made to the beta version - actually I thought that it would have occurred in the beta version before it went live to the non-beta version and since it has been at least a month, that all the various servers would have received the update. Patience is a virtue and I apparently am not virtuous.
Don't expect it to go live to all players in it's current form,
As far as we are told the testing result does not look promising without the reason why,
But the most likely reason was figured out by players.
The main problem currently is the disparity between NH in the new system and on the world map.
The most active players already use mobile for NH, so nothing changes there, but there is a group who just plays on a PC, this group started to do less NH since the introduction of the new system.
In the past all NH was a burden and players gave NH to there fellowship members and to regulars on the world map, now they only give NH to those in the notification bar. if one of those "regular players" does not give NH for a day, or if thet NH notification was pushed of because of trades that player would no longer get NH help that day. if that other player is also in de tresting group you can easily see a downspiral in NH help.
Some people confirmed this theory stating that they give less NH atm because of this reason, after flying trough NH, there are just to burdened to go to the world map to slowpoke themselves trough the "regulars" therefore ignoring those players now.
Therefore it's likely that the current testresults will be a failure.
I wish that they extend the feature to also the world map. this would solve it, and I would love it to not being forced to give NH on mobile exclusive.
