...and now v1.05 is now updating DJI correctly once again. I unzipped using Gary's instructions and made the correction Nick suggested. Thanks guys!
Much appreciated as I like this widget's UI and layout a lot. Not sure how I ended up with v1.05 as it was v1.03 last week. But I have v1.05 and still needed to unzip and fix the "Main.js" file by replacing all occurrence of "ywidgetv2" with "ywidgetv3".
In conjuction with Gary's post below, instead of deleting all those lines - you can instead change the text in all the places mentioned in his post from:
ywidgetv2 to be ywidgetv3
Seems to be working when I changed this. I assume they forgot to change this when they updated to v3. Not sure why this fix hasn't happened on this website when it took me 3 minutes to do myself.
