Hello, 96,486 is really big count of SMS. It is possible that the processing of such a number of items takes a long time and it is possible that server terminate the communication due to a long time without response from the device.
We are curently working on optimalization of application, which may solve issue like yours. We will release new version of app asap, within a few days at the latest. We will contact you. Please, be patient.
Thank you-
Hello,
we developed a promised new beta version (3.4.3) of app. This optimized version should solve your reported issue. Please, download and install new version and try to sync again with it.
I recommend, plug in charger during sync, because sync of big count of items take long time and it is possible that Android system will try to limit the app due to battery life.

Please, send us feedback, if it works now or not.
Thank you for your patience and cooperation.

My phone has 96,486 SMS that has to be backed up but the process keeps terminating due to "internet connection lost". My fiber internet access is quite stable so I don't think disruption is the cause. Is there a way I can back up the sms in parts? mebacal1960, 19.10.2020
