I rooted my phone using Magisk Delta and installed all the necessary components, including LSPosed.
I used a repo (https://modules.lsposed.org/module/io.github.tehcneko.sslunpinning) to bypass SSL pinning and it was successful.
I can intercept all HTTPS traffic from the app except when it involves the WebView component which triggers an onReceivedError (ERR_FAILED) and gets stuck on it.
Has anyone else encountered this issue?
