So after importing the unity advertisement package i get this warning, as you can see the two assets stated there are the exactly same which in itself is weird. And also, when i go to that location (Packages/com.unity.ads/), there is nothing called LICENSE.md!
GUID [4c6fe94acbb24417c988bab18cbd5209] for asset 'Packages/com.unity.ads/LICENSE.md' conflicts with:
'Packages/com.unity.ads/License.md' (current owner)
We can't assign a new GUID because the asset is in an immutable folder. The asset will be ignored.
