Hello, when you posted the question, I was also researching this issue. I was so anxious last night that you must be using the mobile version. This morning, I was still researching and even used the computer version to log in and collect. Only about 20 collections can be displayed on the website, and the rest are gone! I left a message to customer service but there was no reply. I think we are not the only ones who have this problem. I guess it is a technical problem. I have collected 300 recipes. I cry! Now I have researched some. Do you remember if there is an updated version of the front end? I suspect this is the problem here. If you log in to the web version and click on the recipe to add it to your favorite, you can see this recipe in my collection at the same time on your mobile phone. This collection can also be displayed, but if you execute the collection on your mobile phone, the collection of recipes cannot be displayed on the mobile phone and the web. You can try it. As for how to view the previous collection, I am crying without tears. All my hard work is in it! So I suggest you wait and see what happens. It should be a compatibility issue during the version upgrade. It is definitely not just us. If there is no technical improvement, there is nothing we can do. . .
