There were previous versions where you could update multiple separate posts with one form submission. Of Late this doesn’t seem to work, it now only works with one post id… It used to work fine before, it no longer does work.
Hey there 
,
I can confirm the bug and have just fixed it. The fix will be included in next week’s update.
If you need the fix sooner, feel free to send over login details using the [sensitive] tag, and I’ll implement it directly on your site.
Kind regards
