We haven’t encountered this in the test environment, but real users in the production environment have dozens of such cases every day recently.
We also noticed that WeChat and Alipay seem to have addressed this issue recently, but we couldn’t find any relevant content online, so we came to ask what’s going on. Is it a WebKit issue? Will it be okay to simply repackage the app with a new webkit version? Or does R&D need to take additional operational measures? After all, this API is a very basic one and has been supported since iOS6.
