"Press and hold to confirm you’re not a bot" - solution that worked for me
I was going crazy after my chrome-based desktop browser asked me to log back in to TextNow. I had already deleted my cache, cookies and site data. After failing the captcha test for the nth time, I pressed F12 and opened the developer tools panel. I clicked on the Network tab in preparation to watch if I could learn anything that could help, then pressed and held the captcha button expecting to fail again, but... instead I passed!
Was it coincidence? Maybe just opening devtools is enough, but was curious to see if it helps others.
update: oh neat, I confirmed it... I opened an InCognito window and repeated the same results, I only had to have devtools open for it to work. Ah, I just noticed, I have 'Disable Cache' checked on my Network tab from something I was working on before, I bet that's the key.
tldr; press F12 to open devtools. have 'Disable Cache' checked on the Network tab.
