Maybe you're the one that needs some humilty and take some moment to think again.
I took the screenshot from the OP and highlighted the important part to show YOU that you're wrong.
Instead of insulting people you should provide or show the correct way of doing the link-account with a signed apk version, that would be more intelligent and useful.
I already did
here and
here. If using a signed APK is too difficult then use the unsigned version and be glad this exists.
Instead of defending people begging for help you should also help them. You probably don't know how to do it either though or else your posts would actually have a sense of competence other than "this man is saying mean things to people who can't use the forum"
Use the unsigned version or learn how to use the site to understand how to install a signed version and what having a "signed apk" even means. Cheers, mate. The search function is the top right corner of the site
