Bid Submission Issue Resolution

As a client, I'm experiencing an annoying problem - I'm unable to submit bids on projects. This specifically happens when I try to include attachments to the bid. The options for submitting bids seem to vanish, preventing me from progressing. It's obviously a real issue that's restricting my activities on the platform. I need a savvy problem-solver proficient in web-based application troubleshooting. Ideally, you should have a keen eye for recognizing and fixing such anomalies. Key skills needed:

- Problem-solving
- Web/App troubleshooting
- Attention to detail
- Experience with bid platform operation would be a bonus.
