Our facebook page suddenly got limited overnight for no apparent reason causing the error in ad delivery . No account restrictions flag were shown, and Meta rep said everything looked clean from her end, which we then suspected it was a bug and scheduled for a technical support. The reason they came up with is our page is limited???
" Facebook features have some built-in limitations to ensure that fake users/bots do not take advantage of using the feature. Sometimes, when a legitimate person is using the feature too fast or too often, it will seem suspicious to the system, which then places either limits or a temporary block on the feature."

And that's it, no solutions, no next steps what soever, I really dont know what to do, can somebody shed some lights on this matter please?

Many thanks
