Here is the official tutorial for DA:I tapestry.
Not a fan.
Depending on the playthrough you loaded, you may not see all the tiles in the DA:I tapestry at first. The spoiler gates are designed to remain in place until you complete a plot or quest. For example, if you romance a character, the romance tile will remain hidden until you finish the romance (at or near the end of the game). Depending on the choices you made while playing Inquisition, each plot or quest may only have one tile visible (representing the choice you made), while the other tiles are hidden. You'll be able to see if a plot has other options, but you won't be able to see what those options are. You also can't click the context '?' button until you have completed all choices for a particular plot or quest.
