It has come to our attention that a number of our customers are having and issue with the app saying that the subscription needs to be paid, but in fact it was already paid by iOS auto renew subscription as it should have been.
We apologize for the issue and here is how to solve it.
If you are already signed into syncing, sign out and then sign back in again. <== this is what most customers do to get it working again.
If you are not signed into your Syncryption account make sure you are and that Syncing is "on". You can find the Syncryption password in you search for "Sync Info" in MEO. Or reset it here:http://someoprosync.herokuapp.com/users/password/new
Then as you configure the app from scratch, after you create the app access password, go to the Sync tab and sign into your Syncryption account.
Also, check that you are signed into the same syncing account on all devices.
Again we're sorry about the issue and are looking into why it is happening.
