I have a CMS that created with Apostrophe 3 and it's already working fine previously. But I have issue appeared in a few days ago that not showing any modal when I click on the admin bar to see the list and adding new record for my CMS (sometimes only showing the loading overlay, but the modal still doesn't showed up). I see that Apostrophe 3 already a hotfix for this kinda issue (i using chrome too) but it still doesn't work even I already update the Apostrophe package, I figuring out that if you make the connection slower (i did this with change my network to fast/slow 3g in chrome dev tools) it will works and the modal will show up.

Can someone help me to solve this issue?
