I am missing transactions from Mexx
I uploaded using set up autosync, all kraken pulled through but none for Mexc.
I have tried to resync wallet from the start to capture these transactions.
Thanks for your message! 
Unfortunately, MexC has some limits on their API which can make it unsuitable for a lot of people:
If you’ve been trading for a while with them, it will be a case of switching to using the CSV files instead:

Once you have the files, delete the API wallet and recreate it using the CSVs. That should be much more accurate.
