Thanks for letting us know, @princeahmed. We are looking into it.

[princeahmed]

@vovafeldman I am going to release another update of my plugin. Should I use the old version SDK - 2.4.5 with the new update of my plugin?

[vovafeldman]

@princeahmed, reverting to older SDK versions is not a good idea. Better to wait for a fix.

@princeahmed We investigated the issue but didn't manage to reproduce it. Could you please contact us via [support AT freemius DOT com] with additional information on the issue so that we can investigate further?
