Even though I'm not in the hardware business but the software business, I've been meaning to say for a while now that these responses (many similar ones over the last months and even more) simply make no sense.
It's not that we don't believe you that they're true, as in, that you're not given this information. We believe you. It just doesn't make sense that as the customer facing representative of the company you're not given this information. More importantly - it needs to change!
Ultimately, this info (at least an estimate) exists somewhere. Not only somewhere - but specifically somewhere within the confines of the company you work for. If for some reason they choose not to relay this info to the forum support team - they're preventing you from doing your job properly, and are (hopefully inadvertently) reducing the quality of service TP-link customers are getting - well below what's customary in the industry and what customers are entitled to expect.
Please relay to your managers, and ask them to relay that to their managers, and so on and so forth - that not having any sort of ETA is simply unacceptable. That there's a growing number of unsatisfied customers waiting to hear on this issue - that aren't willing to accept "just wait and hope for the best" as an answer. At some point, someone high enough in the org will either know the answer, or know who to relay the question to to get an answer.
The fact that it took years from the first M5 beta and until a final GA - combined with the fact there hasn't even been a single X20 beta firmware yet - doesn't instill a lot of confidence either, to say the least. For all we know, it may be 2024 before we get a production quality X20 updated firmware - which in itself would be unacceptable.
I'm sure I'm speaking on behalf of many people here in the forums and even more people that aren't here in the forums - X20 owners as well as many other Deco models that haven't been updated in ages:
We want an update regarding what ETA we can expect, and we also want that ETA fo be sensible - and not years away. And unless you can point us to another avenue on how we can obtain this data - please find the way to obtain this information for us - it does exist in the company you work for, and we're counting on you.
