Copy / Paste stops working after long RDC sessions (Mac)

Good news! Your welcome! Thanks for your feedback, another reason for the same issue and a solution!

Update, and special thanks to Robert_de_Vries . While I don’t use any 3rd party clipboard managers, I did have the remote machine (windows 10) set to use the clipboard history. I turned it off and have not had the problem since. (!!!) 

Thank you again and I hope this helps someone else. 

Thank you Robert_de_Vries . Unfortunately I’m not running anything like that, except for a password manager (but I don’t use that all that often during the day). I will consider that as a possibility though. 
Actually, I’m almost always copying from Azure Data Studio (Mac) and pasting into RDP when it fails. 

Hi x_brett365, it took a while but I found a post from someone who solved his issue with M-RDP when he closed a program which 'copied' clipboard to a list. Software like CopyClip.

In my case it was Parallels Toolbox, this toolbox also has a feature which is capable of saving clipboard history and when I quit this APP the issues were gone. Maybe you also have such a program running ...?

This is still an issue. For me it's about 20x per day. Please fix this. 

Same here, really frustrating! Please fix this!

Please fix this..this issues happens to about 50 times per day...not kidding...

I'm seeing the same issue in macOS RDC version 10.7.6 (1972).
