Your project
Preview
The preview is how you tell whether the build is right. It is the site or the game, not a picture of it. Only you can see it until you publish.
What you are looking at
After a build finishes, the preview shows that version. Click through a website the way a visitor would. Play a game the way a player would, with the keyboard and with touch.
The preview can be ahead of the public link. Publishing is a separate step. People with the build3.site address do not see a change until you publish it.
Reload
If the chat says the change is done and the preview still shows the old page, press Reload in the preview toolbar. That is the control above the preview.
Refreshing the browser tab reloads Build3 itself. It is not the same as Reload. Use the toolbar control first when the preview looks stuck.
Phone width
Most people will open a published link from a phone. Look at the preview narrow before you publish a website. If a button is missing, a price is hard to read, or a menu covers the page, say so in the chat.
On your own phone, the Preview tab is that same view. Chat and Tools are the other two tabs. You do not have a second project on the phone.
The badge on the preview
The preview can show a Made with Build3 badge. Taking it off is a paid unlock on that project. The price is on the pricing page.
Removing it in the preview does not by itself update the live site. Publish, or update the live site, after the badge is off if people should stop seeing it.
