I have this problem with my lightening cable not being accepted as a supported accessory.
Lightning to aux cable not supported.
Those cheap cables are not recommended for exactly that reason.
For that purpose it is recommended that you use an original oem or authenticated official apple.

So frustrating i may have to go to android phone but then i lose all my downloads.
Lightning to 3 5 mm headphone jack adapter system requirements works with all devices that have a lightning connector and support ios 10 or later including ipod touch ipad and iphone.
Rather than risking it and throwing away money just buy a cable that will work.
If none of the above work and your iphone keeps saying this accessory may not be supported try contacting apple.
And in case the cable becomes old then it is better to try to use a different cable.
Try different lightning cables lightning cables play an important role during the charging process but any wear or tear sign might cause the problem.
