Possibly a hiatal hernia has developed, as GERD is a common symptom of that irrespective prior WLS history. An EGD (endoscopy) would establish that as well as anything else that is going on in there; possibly an imaging procedure like a barium swallow to look at shaping of the sleeve and associated connections can help to establish how things are flowing and why backups are happening. Your primary may order those things or refer you to a gastroenterologist to track down that problem, then they can start considering solutions - fix the hernia, resleeve to correct shaping problems or revise to an RNY.

The pressure in our little sleeved tummies is different than the pressure in a regular tummy from the things I've read. This can cause reflux to happen. Plus the acid our stomach produce when larger is the same amount produced when smaller, so basically we have more acid than we need. There are better PPIs than Prilosec, have you tried Protonix or Dexilant? I have had much better luck with these.

RNY revision for reflux is a good option for a permanent solution. They'll probably do imaging to prove you have reflux (an upper GI series) and an endoscopy to check out the status of your stomach and esophagus. Insurance usually requires these before considering approval of a revision. I wish you much luck in finding a solution!!
