My eyedrop tool is missing from the tools palete (Advance/basic or costum).
I reseted illustrator preferences, reseted tools but it didn't work.
Can anyone help me please???
I rolled back to version 25.0.1 and it solved the problem. This is a bug from the version 25.1.
Do you have anything from ESKO installed?
