Payment doesn't work on Invoices

When trying to pay via Mollie I get the following error:
Error: Request failed with status code 403

When I try the payment in Incognito mode, it works...
I already contacted the developer of the Mollie app and he told me the same:
Hello

Issue is not related to the Mollie app.
You should notify to Akaunting team.
If you view signed link via browser on incognito mode, it is working properly.

Hello,

You can not access the signed URL after logged in, that's the purpose of the signed URL. However, in the next version, your customer will be redirected from signed to portal invoice page if they're logged in:

https://github.com/akaunting/akaunting/pull/1474

New version will be released within a couple of days.
