I'm buying the bounty through the app (while I'm tower or orbit!), paying the glimmer -- which is reflected in my account on the game itself -- and when I look at bounties the bounty is not present. It's taking my money and not giving me the bounty. Super frustrating to pay and not receive.
Cant say Ive seen this one before however in the past when you are having issue with bounty acquisition from the companion app signing out of the app completely then uninstalling (followed by installing and signing back in) the app seems to fix quite a few issues. I would try that and see how you go.
