The reason for this situation is that the cache of the user's mobile phone is insufficient.
Solution: When this problem occurs, it is recommended to restart the phone to release cache resources, and then try to open the "Health Treasure" applet. Or clear the cache resources in time through the related functions of the mobile phone, and then try to open the Beijing Health Baby applet.
2. When entering and leaving Beijing, the "Health Treasure" itinerary verification can't get the green code normally.
The reason for this situation is that Beijing was not filled in when the itinerary was verified, or the itinerary was not completely filled in, which was inconsistent with the itinerary card.
Solution: Fill in Beijing. If you forget or are not sure about the recent itinerary, you can click "Click Query" in the prompt at the bottom of the page, and keep the itinerary consistent with the query results when filling in.
