Check at the "statistics and reports" if the like function is failing.
Access your Instagram and manually like some posts to check if the Instagram has blocked this feature in your account (the Instagram will inform on your screen if you are blocked and will undo the actions that you have done manually).
By confirming the blockade of your Instagram's like feature, you should disable it at the Instaeasy control panel by the blocking time informed by Instagram, which are generally three (3) days. After this period, you can activate the function again, with the startup speed.
Meanwhile, hold any other active functions (follow and/or follow) to keep the action on your account.
For any other assistance please send a ticket to the support team.
