I am trying to control - mostly - the project resource share setting via BAM, however the World Community Grid is not being updated since weeks. I keep trying to change the resource setting now and then a few ticks up and down, but to no avail.
The results are properly shown in the stats everywhere and my GDPR flag is ticked on the project site, should that matter.
Any hints/fixes/ideas available?

After posting I noticed this is an old question, yet it showed up as unread today! Here's the date info from the post: "2020-01-03 14:58:09". Anyhow, I'll leave the answer. Maybe it will still help someone.

Unfortunately WCG chose to use non-standard boinc pages. This means that not all BAM functions work properly. Specifically, you can't set resource share using BAM. Something that I find very annoying - that's not BAM's fault, it's WCG's fault.
It's also not obvious how to change the setting at WCG's site because their site works quite differently to a normal boinc project.

Once you're logged in, at the top right click Settings.
On the lower left click Device Manager.
Under the column "Selected Profile" you should see Default next to each device.
Click the Default link for any one of your devices.
Select Custom Profile
Scroll to the bottom.
Project Weight is the setting for Resource share. Thankfully the number has the same value as Boinc!

Thanks for the reply! Yes it was old, but I was still waiting
