Related to this existing bug report?

Yes. The same issue.
Could you please share the best solution to fix this issue? @JohnP

As you’ll see from the other thread, although there are lots of reports of the issue, no-one quite seems to know what’s causing it. I’m just another user, and it’s not something I’ve experienced so can’t really help, I’m afraid.

Yeah, I agree to it. Let’s hope this will be rectified sooner in the next release.

Thanks for checking it anyway. Appreciate your support. @JohnP
