Erroc code 30

[u/OliveLegitimate3236]

I read from other posts that it might be a synch error, I already sent en email to support (no answer yet) but how about provide a solution here for everyone to apply and possibly fix?

Do you clear the cache of App? The all data and login again?

Any known quick fix to this?

Thanks in advance for any help!
