The previous GL iNet production firmware I was running on my AR750s was giving me so many problems that the router was not usable in my current environment, so I cannot say if the problem existed or not. I tried out the beta firmware after reading another user reported that it helped him with some similar issues on their AR750, in hopes I could use my AR750s in my current environment. Please see:
Before posting this report, I did a search of the forum, and there were several reports of problems with Wireguard reconnecting in some instances, but I could not find an exact match, so I created a new issue. I feel users need to report issues found in the beta releases if we expect them to be fixed in the production version.
