I have a Surface Pro 11 where the keyboard will not respond when turning it off at night and turning it back on the next morning. The only way I have found to get it to respond is to unmount and mount keyboard. It will not occur when putting it in sleep mode overnight. It will not occur when turning the tablet off and back on when not sitting overnight. I have checked for updates. I have tried cleaning the contacts.
I have contacted support through the Surface app doing a chat session. I was transferred to 4 different departments. More time was spent transferring me then resolving the concern. Yes, the concern was never resolved. The last transfer was to the business department because although I purchased both the Surface Pro and keyboard online through retail channels support says the keyboard is a business keyboard. I haven't heard back from business support yet. I don't know if they will tell me that since the Surface Pro is retail so they will not be able to help me. Another remedy was to reinstall the recovery software but there would be no guarantee the problem would be resolved. I declined since I spent hours installing all my apps.
I also contacted CoPilot but it had the usual remedies. I do not want to mount and unmount the keyboard every day to use it. The Surface Pro and keyboard is still within the return period.
