Jetpack not connecting on site | Possible Conflict

Hi,

I am currently seeing the following error in chrome developer console and it seems to be preventing Jetpack from properly connecting on my account, which is also causing Site Health issue which comes up with following:

Error?smoothmind is not connected.: 200

We recommend reconnecting Jetpack.

I have reconnected and in the status of the connection, Jetpack shows all okay. However, coming back to developer console, the following comes up 

admin-bar-v2.js?ver=13.1.1-202407-lite:1 Missing data from PHP (wpNotesArgs).

This is a snippet from the full code:




(function() {
if (typeof wpcom === "undefined") {
window.wpcom = {}
}
if (!window.wpNotesArgs) {
console.warn("Missing data from PHP (wpNotesArgs).")
}
const e = window.wpNotesArgs || {};
const t = e.cacheBuster || "none";
let s = false;
let i = e.iframeUrl || "https://widgets.wp.com/notes/";
let n = e.iframeAppend || "";
let o = e.iframeScroll || "no";
let a = e.wide || false;
let r;
let c;
class l {
constructor() {
this.el = document.querySelector("#wp-admin-bar-notes");
if (!this.el) {
return
}
this.hasUnseen = null;
this.initialLoad = true;
this.count = null;
this.iframe = null;
this.iframeWindow = null;
this.messageQ = [];
this.iframeSpinnerShown = false;
this.isJetpack = false;
this.linkAccountsURL = false;
this.currentMasterbarActive = undefined;
if (window.jQuery && window.jQuery.fn && !window.jQuery.fn.spin) {
window.jQuery.fn.spin = ()=>{}
}
const e = document.querySelector("#wpadminbar");
this.isRtl = e && e.classList.contains("rtl");
this.count = document.querySelector("#wpnt-notes-unread-count");
this.panel = document.querySelector(#${r});
if (!this.count || !this.panel) {
return
}
this.hasUnseen = this.count.classList.contains("wpn-unread");
if (window.wpNotesIsJetpackClient) {
this.isJetpack = true
}
if (this.isJetpack && typeof window.wpNotesLinkAccountsURL !== "undefined") {
this.linkAccountsURL = window.wpNotesLinkAccountsURL
}
const t = e=>{
e.preventDefault();
this.togglePanel()
}
;

Currently I have another plugin active that I believe is conflicting but not sure. The plugin is called ‘Coming Soon Page & Maintenance Mode‘. I can’t disable their plugin as my site is due to relaunch and it is serving a holding page in the meantime.

Is there a way to resolve this error?
