Hi, I’m having the same problem.
My samsung Galaxy S7 is shown as belonging to an organization. Murena MDM is activated as a device admin app in the security tab and shown as deactivated in the accessibility one. Therefore, It can’t be deactivated when going in the security tab (the option is grey). It’s a pain in the neck as parental control cannot be activated as well as work profile.
Besides, when i click on mobile device management in the system tab, MDM app shows up and ask me to enter an ID that I’m supposed to find on the murena MDM page (https://mdm.murena.com). However, i’ve never setup this. See my orignal post here.
Thanks for your help !
