 Error reporting is still supported, but synchronous calls after Bugsnag.start() will no-op. This means Bugsnag.leaveBreadcrumb(), Bugsnag.setUser() and all other methods will only begin to work after a short delay.
+Plugins are also affected. Synchronous calls to Bugsnag.getPlugin() can be used as normal, but plugins may not report errors and set contextual data correctly in the debugger.
 
 This only affects the remote debugger. Execution of JS in the normal way (on the device) is not affected.`
