Hi Prakash Parmar ,
Thank you for reaching out to the Sophos Community Forum.
To clarify, are you currently using the Sophos Mobile On-Premise on your mobile devices? This product has been retired on 20 July 2023. We suggest migrating to Sophos Mobile managed in Sophos Central. With Central Mobile, you can create configurations to block specific apps, including Google Drive.
We regret to hear about your experience, and I haven’t found any recent cases under your registered Community email. Would you be able to share the case ID?
Also, have you tried the following KB?
No, we haven't tried this because we want to block Google Drive specifically, and here in this, it (Block online storage applications and websites.) might impact other services also.
Yes, we have raised a case in TAC, but as per TAC, it is not possible to block Android APK, which is not in the list of application categories (mobile applications).
Case id: 07035904
Thank you for sharing the case ID.
Upon checking, the case handler said they'll add this as a Feature request under your account.
For a workaround.Since this will only be in a specific zone.
Kindly try to make an allow Rule first for other sites or services that might be affected. If applicable
Or, another way is to use Sophos Central Mobile, as this product is specifically designed to manage mobile devices.
