AddOns not Saving data

[Athan]

This seems to be a generic problem with many Addons now 1.7 is out.

MobileFrames in Cosmos has it, at least with the Buffs frame. Although I'm only using that because MoveAnything! has an even worse problem.

ShardTracker (non-Cosmos version) is also not saving settings.

Has anyone found a generic reason for this yet, i.e. a fix that can be applied to any AddOn ?

thanks,
