Try installing an older version, login and then upgrade too the latest version.

Maybe an older version of WhatsApp does not have the check that is blocking you from logging in.

Also, there is no adblocking or alternative dns that is blocking some calls to the WhatsApp server?

I have this vpn because it comes for free with my Google Drive subscription. I have never used it because it does not do what I expect it to do

• privacy, it’s Google.
• pretend to be in a different country is not available

Nice. Instantly bought the adfree version.

I’m using Night Owl. Works nice. You can set schedules, change the filters, shake the phone to stop the filter.
