Invite only

[#1]

So I have sent a proposal for a public job posting on August 3 2023. Then on August 4 2023 the job post turns into "Invite only" and 1 is already hired. Is this some kind of glitch on upwork feed? I felt like I've wasted my 16 connects for a job that turned into invite only.

No. It is editable. Client posted public job, got lot of spam, edited it to invite-only.

Can you elaborate how this become a "got a lot of Spam" on client perspective?

[#4]

Spam applications with templates from bots. Or sometning like "I need this job, hire me!!!!!!!!!!!!!!!!!!!!!". Client readed an 50 such messages, deleted it then edited job.

isn't that just  normal ? it's obvious that when you post a job expect that a lot of freelancer will send their proposal, that's why there's a "personalized cover letter" to filter out the proposals.
