My feelings about Synchrony changed dramatically after I returned to this forum, following a multi-year absence. Since my return, I've heard horror story after horror story of mass-closures hitting various customers, and the thing that always stands out is that there's no apparent, good, logical reason. So I went from thinking Synchrony was fine (although its APRs are very high), to thinking it's an awful company, and wondering when the shoe would drop for me.
Today I logged in to check the activity on my Synchrony Home card; I had recently used it (to keep it from being idle) and wanted to see its balance. So...as I'm hovering around the 'request increase' button under my credit limit, I decided to click it! I thought, why not poke the Synchrony bear?! 
My limit was $9,000 and when asked for my desired new limit, I put $12,000--I didn't expect it to be approved, but I thought perhaps they'd counter with $10,000 and that would be fine, as I'm working on getting all of my cards into 5-digit CLs. Surprise!!
We are pleased to inform you that your credit limit has been increased.
New credit limit: $12,500
Previous credit limit: $9,000
Sure, I'm happy about the CLI, but that's tempered with the knowledge that the proverbial shoe could drop at any moment. 
Congratulations 🎉🎈🎊 on your CLI
Grats on moving up your Home card!
Congratulations!
Congrats on your Home Card CLI

Reason? You mean you're supposed to have a REASON to get a credit card?! 
No, but seriously, I wanted both so I got both. They're separate, distinct accounts--as they'd have to be, since one is a Visa (and has to start with "4") and the other a Mastercard (and has to start with "5"). Both of them have apparently been bucketed. Neither one has gotten a CLI in ages, and every request yields an immediate denial. I've gotten to the point that I'm actually thinking about closing both of them, as they're among my lowest credit limits and since they're apparently never going to increase, what's the point? For the most part, I don't even use them any more. *shrug*
