I heard the same..
FL put out an update in their User Guide to PAUSE the accounts for 24-48 hours. And to reduce the like actions to 200-350 per day with an increased range in delays (55-75s)
If it still persists, to keep it paused for a week and try again.
I tried with some of my accounts, and they are still not working 100%.
Will check back in a week's time..
But F/UNF still working fine on proxies.
