When I rename “Dropbox” to “dropbox” in https://www.odrive.com/account/myodrive it fails with “You already have a link named dropbox. Please enter a different name.”. There’s a workaround to rename it in two steps, but it would be more convenient to be case-sensitive and allow renaming it in one step.
Thanks for the report @bohumir.zamecnik.
As you said, you can work around it with an additional step by adding an extra character to the name and then removing it, but it would be more easier and more intuitive to allow this in a single step. I have made a not to the product team to keep this in mind for rename operations in the next generation odrive product, which is in development now.
