Currently, some experiences will not appear in the Continue page, regardless of how long ago I may have played them.
In this specific case, I am trying to test changes to the mobile gameplay for our experience and the development place simply does not show up in the Continue tab at all on mobile (despite mobile access being enabled). This is extremely disruptive to my workflow since I cannot test these changes properly in Studio.
This issue effectively turns the “Continue” sort into one that does not allow you to continue your previous gameplay.
Temporary workaround: use search and then the Recently Visited list
