Thank you, appreciate that... It really helps to test things before next release. Also please make sure you have latest version of app, v1.4.7 can be seen from About page within app. Scheduling post should work for any duration and any number of times, no limits. Checked server logs, it looks like server got overloaded couple of times yesterday, perhaps that caused some issue during your tests. Please give it a try again. Am working on more improvements, will consider adding 6 digit pin code.
