On July 10, at around 12:41 UTC+3, we encountered a bug.
What we did:
On the images of the Feed Image Editor templates, the currency of the products was displayed as “UAH”; we wanted it to be displayed as “Грн” in Cyrillic.
We started by writing two rules for the g:price and g:sale_price attributes.
Find and Replace > Attribute > UAH → Грн.
Note: This method worked without problems on other projects.
After doing so, everything was fine for many products. However, on some, we noticed that the currency in the images was displayed as “р” instead of “Грн,” as expected.
Initially, I thought the problem was with the fonts, but I noticed that even if the templates had the same fonts, the problem could appear or not appear.
The only correlation I could find was that some templates with the error had a “round numbers” rule applied. Logically, though, such a rule should not affect the display of currency.
Note: The “round numbers” rule was not applied to all templates, probably because its position in the list was not at the very top. I fixed that.
Unfortunately, I did not have time to look into this in more detail because we had to quickly roll back the changes so that the wrong templates would not end up in the ads.
Please help me figure this out.
