I have had an issue with Stores now on two different units. At first I thought there was a problem with the microSD card but now this problem has resurfaced on a unit with an attached SATA drive. I have run into this problems from pre 3.30 to current 4.x ROS versions.
I can almost recreate the issue, here is what happens:
1) Store is detected and listed as an available store.
2) Configure store to be "active" store for Webproxy
3) Let Webproxy run.
4) Store will disappear from stores list
5) Reboot router.
6) Store still be invisible from Winbox.
7) Remove webproxy store (it will say store is "invalid")
Step 8 - Reboot router
9) Store will be visible
10) Now here is where it gets weirder - I can see the store but I can't format, clean, or check drive. It does nothing. If I try and set the webproxy store back on it, it will still say "invalid".
Anybody else have this happen??
