Thanks for looking into this; I appreciate it.

I'd say it started about 3 nights ago (9/23 2030 CDT). Until that point I hadn't even analyzed what company was delivering the ads. I didn't want to approach tech support without having some solid evidence.

Tapjoy tends to air more real life ads (convenience stores, furniture stores, pharmaceutical ads) than "download this app" ads.

The other companies I've seen (IronSource, adchoices) haven't lagged or froze.

Thanks again.
