It happens frequently, which is annoying, I paid to remove the advertising, because I believed in the quality, but this bug makes it unfeasible to use it.
Does it prevent you from uploading the post? AFAIK it always makes you select which community when creating a new post, which would be normal functionality, not a bug.
Could you provide some more detail, maybe a screenshot illustrating the problem?
EDIT TO ADD: Are you selecting “create a post” from your front page, or are you navigating to your community first? If it’s the former, then of course you will be asked to select the community; if it’s the latter, then it should fill in your community by default (while still giving you the option to change it).
Serious,that i got a downvote for asking something? And no answer too… ಠಗಠ
