The last time I had to sync the wallet from the start it took almost the whole day and that was almost 1 year ago now as I updated my PC. Not sure how long it takes now to sync but I'm guessing close to 24 hours or more depending on everyone's computer/laptop. The wallet can take a while to get a connection so just let it sit and eventually it will start to sync.

Is there a working block explorer for TRI as the last one I used to use doesn't work anymore.
