Widgets not showing in their dashboard folder

Hello, I am dev of LNAG widget pack. When building my app i did everything according to the guide, but i have one issue. When the pack is installed all widgets show in the "Installed" tab, the pack even has a launcher icon and dashboard accessible from launcher, but when i try to open the pack folder through the "Installed" tab, no widgets show up. This led to many 1* reviews in the Play Store. I even tried to update the app with the latest template (can't use KAPK because of package name) and the problem is still there (i wasn't able to fix it since 2016). Any help is appreciated.
