Gen3 solved Gen1 (and possibly Gen2?) issues?

After 5 years of using 10 Shelly 2.5 Gen1 devices for roller shutters control, today the 3rd one stopped working. Around a year ago, I had to replace another two Gen1 devices with Gen2. Now the third one is defect, which I should probably replace with Gen3.

Do you know if Gen2 and/or Gen3 improved anything to prevent these quality issues?
The problem is described here https://www.reddit.com/r/shellycloud/comments/13vys0w/signs_of_a_dying_shelly

Beside this problem, I am very happy with devices.
