SpellFlash is not working for me on any character

I'll replace this by LibButtonGlow

Same here nothing is flashing and all i did was log out 2 days ago and today nothing not even a error i can find

Same issue for me. SpellFlash does not work with Ovale on any character, even after I manually updated the SpellFlash.toc and version info for 9.02. It may require an update to SpellFlash, Ovale, or both to restore the functionality, or for a "SpellFlash clone" to be built into Ovale, if possible. In any case, I hope something can be done, because I have used and loved this combo of addons since they came out. Playing WoW without them just feels awful now.

I'm also been having the same issue, but spellflash stopped work when shadowlands was release. on my hunter (marksmanship) the only spell that will flash is Volley. On all other characters spellflash does not work. Any advice?
