Hello,
I’m the developper of an anki shared deck : [GitHub - SKOHscripts/Optimized-Chess-Puzzles: Tactical pack designed as a versatile and scientifically optimized training tool that adapts to several chess learning approaches.](https://github.com/SKOHscripts/Optimized-Chess-Puzzles)
This deck is designed with HTMLTTCHESS, and optimized with Anki and AnkiDroid.
I have never tried with AnkiMobile, but a user recently reported that chess board does not show at all. I thought HTMLTTCHESS would be kind of universal, but it does not seems so.
Do anyone have an idea on how to solve it ? Is there something I could do ?

This bug is being tracked in the Optimized-Chess-Puzzles project via [Optimized-Chess-Puzzles Issue #10](https://github.com/SKOHscripts/Optimized-Chess-Puzzles/issues/10), and it seems that code changes already have been identified that fix/workaround the problems seen on AnkiMobile.
As I understand it, the problems were caused by differences in behavior of iOS WebKit/WebView regarding rendering timing and how malformed HTML is handled.

Yes @BenJamesBen I wrote this issue with my research results. I’m just not sure about everything I found, I’m not sure if that could be a solution.
I’m gonna apply the solution I found, but I wanted to understand the root cause of the problem so that nothing would be overlooked and to prevent this kind of thing from happening again.
