L5 stops workin must replug

I have the l5 ir adapter. Every time the ipad goes to sleep over night and I relaunch roomie the l5 won’t work. Un plugging it and replugging causes it to send ir codes continuosly. I know this from my ir repeater systems talkback blue led. If I unplug and replug a second time then it seems to work fine after that. This is very repeatable behavior.
