I was scrolling what's new in peertube.co.uk instance. It happens everytime I scroll to look at a few videos

Same to me. Google ask me for recaptcha and newpipe will crash when I click the square.

Recaptcha is robot racism.

[Stypox]

Thank you, this is finally a reproducible ReCaptcha that can be looked into :-D

Could you test this apk? The reCAPTCHA activity is shown, even though the website just shows "Too many requests", and the user can then press back or "Done" to exit. @B0pol @Neboer @bleedingcrow
app-debug.apk

[B0pol]

I can't install it, "the package appears to be corrupt."

[Stypox]

@B0pol did you unzip it? For me (on Android 7) the apk installs flawlessly.

[Stypox]

Here is a direct apk download link: app-debug.apk

[B0pol]

Yeah of course
It doesn't install on both my phone and old phone
Your link returns a 404 page

[Stypox]

I didn't publish the release I used to upload the apk, here it is again, sorry: app-debug.apk
