Synchronization Eversync no longer works on my Medion android 5 tablets. Apparently on my android 8. Have you left the support of older android versions or is there a recent one to Julie sever. When I try to synchronize I keep getting the error server

Synchronization Eversync no longer works on my Medion android 5 tablets. Apparently on my android 8. Have you left the support of older android versions or is there a recent one to Julie sever. When I try to synchronize I keep getting the error server error. Furthermore, there seem to me some bugs and improvements in the android versions. I cannot say anything about versions for other operating systems. Greetings Hugo.
