Since June 2022, after a beta update (4.9.9.1159 V2
4.10.9.1159 Pan V1), I started having issues with several events not wanting to upload, playing partially in addition to being jerky. This meant that CamPlus and CamPlus light on my PanV1 and CamV2 were of little use. We tested several firmwares without success. As a temporary fix, I had created rules to restart my cameras twice a day. I have successfully reflashed some cameras to fix these issues. I kept a few to test new firmware.
Then came the missing card problem with new other betas after some reboots. I had to check every day if my cards were still functional. If they weren’t, I restarted the faulty cameras up to 1 to 3-4 times. After that, if still the problem, I reformatted via PC. Everything was working again.
After arrived the problem with some cams that needed 4-5 rebooting to connect again after another firmware update. Sometimes, I had to reset some cams to connect again but rarely.
Yesterday, after updating all my test cameras with this new firmware(4.x.x.1851), all my problems went away. I updated all my other V2 and PanV1 as well. For 24 hours now, all my events have been working correctly. I restarted several times to test the problem of missing cards and I had none. No issue connecting them on my network too.
I have updated my 9V2s and 3 Pansv1 without issues.
I believe that a new public version of this firmware will be released shortly. I continue my tests and I would like to thank the developers for having fixed all these problems, especially WyzeBaohua with whom I had several communications.
Hoping everything continues to work well with this firmware. Otherwise, I will continue the tests. 


Regarding 2.39.0(2.38.4 and 2.38.3), I tried them but returned to 2.38.2 because some cameras take longer to connect(randomly). Some times it’s quick but other times I have to force close the app, return to previous screen or try another group to make them connect again. This problem is not present with 2.38.2.

and all the others.
Edit: 48 hours later, the issue with some events not uploading and not playing started again.
