Works great -- Thanks! Couple of remaining issues:

I will hold off on moving any more serial number proxied Kiwi to the secondary proxy server until you implement connection retry. I.e. if connection to Kiwi URL beginning with [digits].proxy.kiwisdr.com:8073 fails you should try [digits].proxy2.kiwisdr.com:8073. And only if that fails consider the Kiwi to be not responding. Right now only 11 public Kiwi with serial numbers 210xx are mapped to proxy2 and they currently just flash the spectrum and waterfall without connecting. But don't otherwise cause v2.0.59 any problems. An example is "Radio Free Citrus" (21084) roughly the 20th entry in the list. Kiwi with URLs not beginning with a digit won't be moving to the secondary proxy server.

License key entry dialog: When I downloaded the app from scratch (i.e. no previous license key stored I presume) the license key field was empty. When I typed the first character of the key the Android on-screen keyboard offered autocomplete of the last full key it remembered. Just like it might when the keyboard is used for predictive texting. I clicked on the autocomplete key. But the resulting license key, which was entered correctly, results in an "invalid license key!" error. On closer inspection this is because the autocomplete appends a single space character at the end of the key when inserted into the key field. If you backspace to eliminate the space then it works. But this is a subtle thing to notice on a small tablet with tiny characters. So maybe trim trailing spaces from the key before validation?

No, I only have the one Galaxy A9 tablet. No Android based phone. And 1.45.04 works on the tablet. But none of the 2.05.xx versions do.

Seems odd that the license key dialog confirmation hangs with the 2.05.xx versions (valid key never turns the field entry box green, dialog box can't be cancelled). Like there's a generic problem with app network access apart from fetching kiwiservers.js file specifically.

For me 2.05.58 has exactly the same problems as .57 on my Android tablet.

I can open both of the kiwiservers.js files in a browser fine.

From the CHANGE_LOG file:

After updating to v1.826 (or later) Kiwi with serial numbers 210xx (i.e. 21000 - 21099) will switch to running on the secondary proxy server. You still connect to these Kiwi in the usual way, e.g. 21033.proxy.kiwisdr.com or 21033.proxy.kiwisdr.com:8073 But the browser address bar will now say 21033.proxy2.kiwisdr.com:8073 (note "proxy2")

Re: emails from kiwisdr.com

Well, the root cause is that getting outgoing emails working from the forum software used by kiwisdr.com to large email providers like Google et al exceeds my likely remaining life span.

I spent two weeks once trying to get it to work. I implemented and tested all the usual suspects: DMARC, SPF, ... Passed all the tests. Didn't help. I gave up. Too much other important work to be done.

This is why the forum sign-up confirmation page say "if you don't get a confirmation email from us in a day or two just try logging into your account and see if it works".
