My guess would be that the server might not be sending back a Content-Type HTTP header (as opposed to the “<meta http-equiv…” tag within the HTML) or the wrong one. If so, then maybe the WebView is handling that differently to how it did before.
I just did some more tests today. I did a rollback to sdk 32 and then installed package react-native-webview, everything is working fine. So I think its something related to expo asset cause on sdk-32 asset was part of expo package on sdk-33 we have to install an extra package (expo-asset). Is there any sensitive change between these two sks? Specially on “Asset.fromModule”
