Description

Running the latest AGH Edge build on Raspberry Pi 4 ARM64 Bullseye.

Problem:

• Disabling (and re-enabling) Optimistic Cache when not connected to WAN results in AGH hanging/freezing for 10-15 seconds and network connection errors popping up before the setting kicks in.

Note:

• A similar issue (reported by me) existed for other AGH settings, but was re-produced by AGH developers resolved a while back.

Question:

• Where does AGH store Optimistic Cache data? Can it deleted manually? Is it encrypted? I hope its not possible for someone to just open it up and poison it.
