Hi @jbulava! From a streamers perspective this will hurt us significantly.
By preventing concurrent campaigns with no overlapping you will prevent developers from having specific campaigns on their own channels as well as general category wide campaigns. The changes effectively force developers to choose: prioritising either their own channel and events or streamers in the category. Obviously developers will choose their own channels.
I implore you to reconsider overlapping campaigns as this reduces flexibility and will severely negatively impact your creators.
