Static Web Apps returns files from previous deploy

Question

I've been using Azure Static Web Apps with a free sku plan for a long time, everything worked fine. However, suddenly one day I discovered that a request to index.html returned the contents of the previous deployment. The redeploy did not help; it still continues to process one out of five requests incorrectly. Of course, the first thought is about caching, CDN, etc. But the funny thing is that I make the request using a curl, which does not cache anything. Moreover, it doesn’t matter which domain I access - a custom one or an original one - the effect is stable. Out of 20 requests, somewhere around 3-4% return old content. There are no Static Web Apps management tools - they cannot be cleaned, they cannot be restarted, and the contents cannot be viewed. Maybe someone has encountered this - what should I do in this case?
