Activity creation bug in LIghtning Experience

[CnP.Support.AM]

Good day @[email protected]

As of now we don't support Lightning. We are working on compatibility with Classic and Lightning views and will be fixed in the upcoming releases. However, thank you for notifying us.

Good afternoon,
We are working in Lightning for a client and finding bugs here and there. I know you are working on the next release so in case it hasn't come up yet: From a Click and Pledge record (for example: Transactions) when you click on "Activity" button, it opens a pop up task window as it should. But if you hit Cancel it loads a new tab, in Classic, with "URL No Longer Exists" error. If you X out, it just goes back to a blank page in LEX. I'm assuming there's no fix for now, but if there is, please keep me posted. Thanks!
