Anybody familiar with this buggy strands ripoff?

This is more a rant than a recommendation. It's a ripoff of NYT which is fine but it's very buggy.

The words aren't unambiguous and I can't guess the same word twice. Meaning for example I guessed a word that ends in "A" but took the wrong "A" so I can't choose the combination with the right "A" anymore. This is true for at least 4 of the 7 words today! I had to use two devices and private windows to circumvent this problem.

Also I found 6 out of 7 and it's impossible to find a spangram which exists according to the rules and I don't get hints anymore. Some unused words are just isolated.
