In my earlier reply above, and at the topic where you first posted at Brave Community:
You will find members of Brave Support, to whom, you need to address your issues. I suggest that you make note of every Brave Support member, whom you find, anywhere here and over at GitHub (“https://github.com/brave/”).
When you write, here at the Brave Community, it will help you, them, and those of us who do read and try to learn, among many of the issues . . . for you to write in detail, being specific.
You did write in some detail, about some of your steps, but it will help us to know more about items, things, of your abbreviations.
For example: What are an “ewt” and an “ewtB” and a “SEED”?
In my original reply, here, to you, I have referred you to where you would find a member of Brave Support (Mattches). In addition to raising the question of, what version of Metamask, are you using?
Meanwhile, where you first posted, there are at least 2 more members of Brave Support (DouglasHDaniel) (brian).
Try to write formally, with structure; sentences begin with a Capital letter and end with a period. Make sure that paragraphs are not mashed together, nor very lengthy. That helps Brave Support - good writing has a better chance of getting their attention.
What may seem apparent to you, as something that “the right people” would know, here at the Brave Community, may leave other readers here, in the dust. Yet, a lot of people are here, trying to both learn, and help others; many are new posters with issues and Bug Reports.
The system, here, is not a traditional support service desk, where, what you raise as an issue or report as a bug, is picked up by “the service team.”
BTW, at your original post, back in January? There were references to info, re wallets, etc. There is a lot for you to study.
And usually, the troubleshooter is not a member of Brave Support, but, you – having studied here, and tried various steps/tests, and keeping detailed notes re your findings.
Understanding how Brave Support works via the Brave Community, takes time and a lot of study.
PS. When you write a Reply, begin your writing with a simple address to the person - as if writing a letter to somebody. That practice will make it easier for us to see, exactly to whom you have replied. Thanks.
