No, you are not the only one having SD card problems. There’s a known issue (or more than one) with OG cams in particular struggling with the SD cards at the moment. But it is a local issue, Wyze isn’t doing anything remotely. It appears to be a Firmware or app bug. Wyze engineers have been asking people to submit logs for the issue, then post them in the latest fix-it-friday thread so they can pass on the logs to devs to try to get that resolved.
If you have any evidence for anything more than the known bugs they’re in the middle of trying to resolve, feel free to post the evidence. But I guarantee you don’t have to worry about the cloud being in the AC charging adapter (yes, I have taken an adapter apart). It doesn’t even support a data connection. Wyze wants to resolve the bug. If you submit a log it will help them find the issue and release an update/fix.
Submit a log for it in this thread:
