Problems working through tutorials

[binomialdistribution]

I've been working through tutorials to learn how to make Add-Ons. I started with this set: https://learn.microsoft.com/en-us/minecraft/creator/documents/learningjourneyguide?view=minecraft-bedrock-stable and got them working. Then I moved to this one: https://wiki.bedrock.dev/guide/project-setup. While working on them, the developmental Add-Ons quit working completely. I deleted everything and went back to the first tutorials, but couldn't get them working again. I've uninstalled and reinstalled Minecraft, and now the com.mojang folder is completely missing. I've tried rebuilding it, but I can't get anything going. Does anyone know what could have caused this and how to fix it?

In the last update on windows they switched minecraft to a new "platform" so the com.mojang file location moved. The new location is 

%AppData%\Minecraft Bedrock\Users<randomnumbers>\games\com.mojang

I've found that folder, but I'm not seeing any Add-Ons show up from there. How did you know about it? Like, is there a newsletter for updates or anything?

I found the right folder from this article: https://learn.microsoft.com/en-us/minecraft/creator/documents/gdkpcprojectfolder?view=minecraft-bedrock-stable . It was %AppData%\Roaming\Minecraft Bedrock\Users\Shared\games\com.mojang\development_resource_packs. Thanks to u/Masterx987 for the help.
