the embassy is a really good place to start - it’s exceptionally belgian of them to say that british people are able to use the covidsafe tickets and then for it to be impossible to do so! it may be a situation like the french pass sanitaire and it just needed a bit of time for them to integrate the uk certificates that were already accepted independantly.
i note the circuit website points out that the entry requirements for belgium and those for the circuit may differ, which is reference to the uk being a “red” country.
double check your testing obligations for belgium as a british visitor if you are allowed entry to belgium. the british gt event folk had a test when they left the uk, a test when they arrived, and then a test to reenter the uk. all but the one to reenter the uk needed to be pcr, all needed to be paid for.
can’t wait for all this to be at least streamlined
