Same problem, can't comment anything. Every single comment needs a verification, and it just never appears sometimes. This appears in red:
Please check the information you provided
- Please complete the verification to continue
Edit: This probably has to do with me making many comments in a day. The next day, after many hours, it started working again. This has happened to me multiple times, there is a limit to how much I can do this which is frustrating. Just have to wait. If only the verification actually appeared, then this can be fixed.
