Have you went to your app store be it Google Play or Apple, and updated your partiko app recently? Sometimes they add updates and if you miss them it may stop certain things from working properly.
Just a thought not a guarantee fix😀 I loved my Partiko app but since I have so many apps on my phone the memory is full so I had to pick and choose which apps I would keep and which I could live without. And I can just come to Steemit from my browser sooo!!
Talk soon I hope you get it straightened out whatever it ends up being. @bit-trader (Howie)
