I would like to add that there is a bug here as well and in our use case we don’t need the prompt in the first place so would it be possible to remove it? or be given the option in Admin settings to disable it?
The bug is that if you click on the ‘Accept invitation’ for the second time, the page will stay static and not show any message. This is not helpful at all. It blocks the user from using the previous context to be redirected to the topic again. This is a major issue. If I put an invite link in a document and expect that the reader might use the same link over and over again to be redirected to the topic, the invite link will no longer work. 
We use invite links because the participant need to be added to a private category first to be able to read the topic. If the user needs to find the topic again, they should be able to use the same invitation link. In this case it should auto-accept invite if the user is logged in because the invite is intended for that user and as it worked fine previously, should redirect the user to the intended topic post.
Invitation links worked perfectly before. I hope you can have a second look at this and give admin the option to disable this ‘Accept Invitation’ prompt/button message. Thank you!
