Windows cannot sync files to Android at the same time, but Android can sync files to Windows.

Confirmed here.

this issue is still or again present in v1.33.2 of the Android app, although some reported this to be fixed in 1.33.1.

Between v1.32 and the current v1.33.2 of the Android app there seems to be a new bug (or by intention?) introduced, Android devices (tested/verified with 5 devices Huawei,Xiaomi,Samsung), can't discover/connect each other anymore, regardless if successfully paired before or not.

Completely bypassing/disabling Blockada and AFWall+ doesn't have an effect on this either.

Interestingly the desktop app (in KDE, Kubuntu 22.04 and 24.04 and 25.04) is still able to connect and even see the filesystems and battery status and so on (likely all modules) from all Android devices and from Android the modules for remote input work as well.

So "just" the Androids (10-14) don't see each other anymore, which is weird.
I often used that for sharing the clipboard between mobile and pad :-/
Most of the times i use access to the Android's filesystem from the Laptop or Desktop, which still works, so to me it currently is not a major issue, but i think others may see a large impact to functionality.

Confirmed that switching back from v1.33.2 to v1.33.1 is a workaround, tested with 4 Android devices

“Android version” “Device name” “KDE version”

I have four smartphones and a PC 'wen' (please ignore the rainbow-colored black and the funny screen color adjustment). Currently, all four phones can connect to the PC, but the PC cannot share files with the phones, although it can share the clipboard and send pings, with only certain modules functioning. When the PC attempts to share a file with any of the phones, the phones receive a notification about it, yet the file does not appear in the Android file manager. Ironically, all four phones are capable of sharing files with the PC, which is driving me crazy!!!

Version 1.33.1 test connection attachment

In the 1.33.1 version, I tested the connection between the phone 'civi' and the phone 'meizu 21 PRO', but they still cannot connect. As shown in the attached gif, the devices are only displayed for a moment when refreshing the list.

I just tested KDE version 1.30.1, the phones can connect and share files with each other, but they still cannot share files with the PC, and there is also no notification of receiving files in the phone's notification bar.
