Issues with Watchlist

Hi all, I have approx 300 odd listings & am in-trade.  Up until last week, watchers would roll-over when I relist my items i.e item is on someone's watchlist, item closes, item is automatically re-added back to watchlist upon relisting.

All of my listings go back to zero watchers upon relisting now & I know that at least one of my watchers isn't receiving any emails to say the item has been relisted.

I spent quite a lot of time gathering screenshots for TM helpdesk only to be told that the watchlist roll-over is not available for people in-trade.

I can't see anywhere where it states this & TM just keeps closing my help requests after each response they give me.

I sell some niche items & the watchlist roll-over suits me well so buyers don't have to search all over again. 

Has anyone else had an experience like this?

Thanks!
