Can you confirm any available updates from F-Droid for microG are applied?
I can indeed. No available updates for MicroG in the IodeOS repos. I even checked the MicroG repos as well just to make sure.
If you can “Long Press Icon > App Info > Clear Storage” for microG it may help? But I don’t know of other microG issues with this anymore?
I tried that a couple of times but it made no difference. I also tried toggling pretty much every MicroG option to see if any of them would stop the crashing but nothing worked. I reflashed the stock OS for now as it was crashing too much for the phone to be usable.
