Hello I'm new to Thunderbird for Android. And I'm not really well versed in using all of the options of Gmail. But what I would like to know is how can I sync my folders such as trash or spam with my Gmail account using Thunderbird for Android? I went in and clicked on the sink button to let them sync but they're not doing it. For example I deleted an email and put it into trash but I'd like to archive it. When I go to move it it tells me I cannot move anything from a folder that is not synced. I've searched all over the internet to try to find an answer and I've had no luck. Anybody know what could be the issue?
