All the themes I have purchased are gone after I upgrade my phone or log in on a new phone

Ensure that you have logged in to the account that you used to purchase these themes. In this account, you can search for the purchased themes and touch BUY () to download them for free.

If the issue persists, it is because theme has not been adapted to the latest EMUI version. Please provide our customer service with your HUAWEI ID and EMUI version. We will process the issue and inform you of the result ASAP
